Yes, but there is a catch which to me would rank them in the "close but no
cigar" category:

"TiVo also unveiled TiVo-to-Go, which lets users who also subscribe to an
additional TiVo home networking service to transfer shows they have recorded
on the set-top box to a home computer. The system is kept secure by a unique
key-sized memory device that must be plugged into the computer when the
recorded content is watched or copied."

So watching what you transfer requires a dongle? Forget it.

Watching it by playing the file on your computer requires a dongle.
Once it's burned to a DVD, you can watch the DVD anywhere (PC player,
consumer DVD player, etc).

Sorry, that makes no sense to me. Does that mean you HAVE to use some sort of
special DVD player software to view the DVD? Don't you think it might be that
you just need the dongle to transfer the video to the PC?

Once there, (if you can already burn to a DVD,) there can not be a limitation
on viewing it, because the DVD player (like Win DVD or Media Player 9,) does
not care if the DVD is a file on the HDD or in the DVD drive. This would
interfere with regular DVDs being viewed, which makes absolutely no sense to
me.

My guess, (and it's just a guess here,) is that the software will be an add-on
to the existing HMO desktop software we currently use to publish images and
mp3s on our TiVo. It currently requires a TiVo ip address to be present. My
guess is that before you can see the video you want to copy to your PC, the
software has to see the key on the PC as well.

Read the Tivo press release about it as well as other material on
Tivo's website. It clearly states that:
(a) to play the *file* (NOT THE DVD) you have to have
the USB dongle in the machine.
(b) you can burn a standard DVD from the file.
(c) you can play that DVD anywhere, including plain
old consumer DVD players.

Once there, (if you can already burn to a DVD,) there can not be a limitation
on viewing it, because the DVD player (like Win DVD or Media Player 9,) does
not care if the DVD is a file on the HDD


Given the presence of the dongle, I'm going to bet that the file
pulled to the PC from the Tivo is encrypted with a code unique to your
Tivo account, which is why the dongle is needed (the decrypt key will
be on the dongle). And that's why WinDVD or Media Player 9 will be
unable to play it w/o the dongle.

Similarly, given that they state a burned DVD can be played anywhere,
including plain old DVD players, that would imply a standard DVD is
being burned, without the encyption.

And yes -- I can't see what would stop you from ripping back
the DVD you just burned.

My guess, (and it's just a guess here,) is that the software will be an add-on
to the existing HMO desktop software we currently use to publish images and
mp3s on our TiVo.


It's already been announced it'll be a tweaked version
of Sonic Software's MyDVD.

This is where I think there is some confusion. Once that mpeg file is
decrypted with a key, it should be playable with any player. If you take any
DVD and take the mpg out (just copy it to the HDD and play it,) it is playable
with any DVD player program. I think the "key" simply allows you to decrypt
the previously encrypted mpeg residing on the TiVo. Especially since there is
already a hack for the TiVo S1 that already does this. The "key" just limits
the ability to decrypt to paying customers.

Similarly, given that they state a burned DVD can be played anywhere,
including plain old DVD players, that would imply a standard DVD is
being burned, without the encyption.


Which means one of two things. The file is no longer encrypted or the burning
software does the decrypting. Since we already know it's hardware (the "key.")
That means the DVD files are already decrypted and any burning program will
work.

To give you an example: DVD Xcopy decrypts a copyright protected DVD to a
temporary directory, burns the DVD and deletes the temporary directory so that
the decrypted files will no longer reside on the user's HDD. All the user has
to do is to copy those decrypted files to another directory (or check the box
for an external burner like nero,) and voila, you can use any burner to burn,
or any player to play, or copy it to the Inet, or whatever.
http://www.dvdxcopy.com/

And yes -- I can't see what would stop you from ripping back
the DVD you just burned.


And THAT is just how easy it will be to "work around" the "protection" of
keeping these files off of the Internet. All that will be for us users is a
hassle. And I've been jumping to this conclusion in my discussions here, that
a DVD is simply an mpeg with a menu file. The only protection that would work
for Internet sharing is some sort of decss type of encryption like they do
with DVDs, VHS tapes, and some PPV movies, which will not allow "good" copies.

If in fact there is a decss scramble included with the burned DVD, then you
would just use something similar to DVD Xcopy.

But, if it's all that complicated, not only would it be senseless, it would be
simply ridiculous since one is allowed to use a DVD recorder or a VHS recorder
with ZERO aggravation. I can copy a DVD made from TiVo RIGHT NOW and upload it
on the Internet if I want to. And did I say, it's easy as can be?

Sure, if the decrypted mpeg file was written to the disk.
I expect the decryption is done on the stream, which means other players
cannot access it.

I think the "key" simply allows you to decrypt
the previously encrypted mpeg residing on the TiVo.


I don't interpret it that way. I get the impression that the previously
encrypted mpeg file is copied verbatim to the PC, and the file has to be
decrypted on the fly as the proprietary player plays it.

Especially since there is already a hack for the TiVo S1 that already does this.


The video streams are not encrypted on Series 1 units.
The hack for Series 2 disables encryption of future recordings, it does
not defeat encryption of prior recordings.


The "key" just limits the ability to decrypt to paying customers.


The "key" allows paying customers to view the programs.
Non-paying customers cannot view the programs at all.

Similarly, given that they state a burned DVD can be played anywhere,
including plain old DVD players, that would imply a standard DVD is
being burned, without the encyption.

You're not making sense. We know that a piece of hardware (the "key" or
"dongle") has to be plugged in to view the files. We do not know
whether the hardware does all the decrypting or if it simply provides
crucial information that the software needs to do the decryption. I
expect the latter. You cannot use simply any burning program because
the decrypted data is not stored as a file on disk.

Indeed. Actually, unless they CSS encode the DVDs, it may be even
easier than that.

Note that the MPAA considers DVDxcopy illegal under the DMCA, and is
trying to shut it down.

(Financial Disclosu 321 Studios has promised to donate $25 to the
EFF for each copy of lite-on and dvd X copy platinum bundle sold)


This is part of an interesting philosophy among some of the forces on
the MPAA side. Some want an absolutely locked system, closing any
window into it they can find. Others prefer the "speed bump" approach,
they just want to make it a little harder but know that anybody
determined will get a copy.


Both approaches have numerous downsides. The complete-lock folks will
never attain their goal, and may in fact be a feint, to get the speed
bumps. The speed bumps seem to just make things harder for everybody
and gain little for the studios -- unless they can shut down filesharing
networks, since all it takes is one determined copier to put a a file
on Kazaa.

Some people may also take the speed bump approach because they feel they
have to have *something*, even if it doesn't work. Or they may feel it
reminds the user that they might be infringing. I will give this idea
some credit. For example, the DRM on most of the online music stores
lets you burn a CD with the songs you download, from which you can of
course then rip a completely unprotected file. But in doing so you
won't get CDDB data and you must transcode, and that is enough to stop
people, they hope, when the retail price is under a buck.

It also interfers with people legitimately wanting to play an AAC song
from iTunes on an mp3 player that doesn't do AAC.

This is an important distinction, because it seems that with this dongle
approach, only the Sonic software can decrypt and then burn the video
to DVD.

The problem with this is that current TiVos (except for DVD recorders with
TiVo software built-in) do *not* store the MPEG-2 in a format that can
just be "copied to DVD". It *must* be re-encoded. As we all know, some
programs do this well, and some do it poorly, but even the very best result
in a loss of quality.

This is one case where limiting the choice really does harm the user, because
some of us have spent a great deal of money on really good MPEG encoding
solutions. Not being able to use them is a bit of a pain.

Indeed. Usually that capture card in your computer could have recorded
it right off the air too, for even better quality. The method you
specify involves the risk of "transcoding" -- two different compression
sessions on the same data, adding the aliasing of both to the result.
It is not as good, which does not mean to say it's always horrible, but
it's a loss of quality for no good reason.

It's also a pain to do what you just described, and must be done in
real-time -- hour show takes an hour to copy.

They like this of course, they want it to be harder and lower quality.
We, on the other hand, would like the convenience of just saying
"copy that file on my disk to another disk" which is really all that
should be going on.

The sad part is it saves them nothing, since what you describe is
possible, and while it does have the quality reduction, if you were of
a mind to give the show away free, you could put your copy on Kazaa and
soon there would be thousands of people. Only one person has to do it.


Their plan, by the way, is to get a law in place so that all capture
cards will be required to look for a "watermark" in the analog video and
audio streams, and refuse to digitize anything with a watermark that
says no.

Failing getting a law, they have a backup plan to encrypt all data and
refuse to licence the decryptor to anybody who won't put the watermark
detector into all their analog equipment.

program stream). The software TiVo is providing to rip from a Series 2 TiVo
might encrypt the ripped video, but that's done outside the TiVo.

They can't do that, as most people don't have Authoring DVD burners. Those
are the big-$$$ burners used by the pros. General DVD burners (the type
you'll find on the shelf at Fry's (or whatever) for $200 or less) can't burn
discs with CSS. The area on a General DVD-R blank where the CSS information
would go is not available.

It's been implied here that ReplayTV does store in a standard MPEG2

Correct, *if* the source is a single layer disc (or you cut down the
content you copy until it fits in a single layer). Doing this, you get
essentially bit-for-bit copies after CSS decryption.

If that's the case, then this becomes even more bizarre. The new
product would in theory then let you burn an unencrypted mp2 to the DVD-/+R,
which is what it needs to burn (or mp1) if you want to be able to play
back in ordinary players, and then read back that plain file from this
non-CSS DVD.

And even though you can do that, the first copy you get has to have
a dongle to play? This makes less sense than before. Ok, it's a
pain to have to burn and re-read, but that's not going to impede anybody
who really wants the full video. Dongles were (mostly) abandoned by
commercial software vendors as not worth the support cost, but at least
they did something, in theory, for their piracy fears.

I doubt this will ever happen. Maybe with digital TV but not for

You make some great points Brad. Maybe at some point it really won't be
an issue. I'm just saying, with all the "hoopla" over TiVo extraction
and fighting "the man" right now, you can pretty much make yourself a
nice qulaity DVD now without a lot of fuss. Now I can watch it anytime
and since it's DVD...any place!

They are not really a dongle. They could make the satellite receivers
stand-alone locked devices, but the problem is they would get cracked and
once cracked, they would have to replace all receivers to fix it. So
they isolate various factors in the smart card, and can afford to send
out new cards to customers in new circumstances, or such is my
impression. (Of course the presence of smart card programming
machines, legal in themselves, has in some ways allowed the facilitation
of more scarfing of satellite and PPV because you only have to hack
the smartcard.)

Since you can't really copy protect software on its own, the dongle
became popular in the 80s as a piece of hardware (which could be
made reasonably tamper proof) to go with the software (which is very
hard to make tamper proof) to stop copying.

However, hardware has support costs, and most companies decided the
support costs of the dongle, and the legitimate uses they interfered
with (such as easily using the program on laptop and desktop) weren't
worth it in terms of saved revenue. Plus you would get multiple
dongles and further problems with those. (In those days most dongles
were parallel port or serial port, and you only had so many of those.)

Dongles persist in a few areas. Video games effectively use them,
selling on cartridges or special CDs. Some specialized small volume
high cost packages use them because if you charge $15,000 for the
software you can afford the support costs of the dongle. But not on
a $40 piece of software -- or so the industry had judged. Games also
kept them because games have higher illicit copying rates than
business software.

So the smart card is not a dongle, but this USB device that is going
to come with the Tivo PC viewer sure sounds like one.

Early dongles, btw, were something the software just tested for
the presence of. Later they would do fancier things like perform
some important function the software needed.

They are not really a dongle. They could make the satellite receivers
stand-alone locked devices, but the problem is they would get cracked and
once cracked, they would have to replace all receivers to fix it.


The DigiCipher II protection on C-Band receivers is built into the
receiver (making it a "stand-alone locked device"), and it is precisely
because of this that it has never been hacked.

(Brad Templeton) shaped the electrons to say:
If that's the case, then this becomes even more bizarre. The new
product would in theory then let you burn an unencrypted mp2 to the DVD-/+R,
which is what it needs to burn (or mp1) if you want to be able to play
back in ordinary players, and then read back that plain file from this
non-CSS DVD.


There is one little data point that is important here.

If the show is copy protected you'll be able to watch it with the
dongle but NOT burn a DVD. Same as on the Pioneer DVD-RW TiVo units.
So they're extending the existing trust model to the PC via the
software/dongle. If you can already burn a DVD of the show via the
Pioneer (and forthcoming Toshiba and Humax units) then you can do it
on the PC.
