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. |

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. |

And that's why WinDVD or Media Player 9 will be unable to play it w/o the dongle. 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? |

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. 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. 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. -Joe -- I love my TiVo - http://www.inwap.com/u/joe/tivo/ |

And I've been jumping to this conclusion in my discussions here, that 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. -- How did "spam" E-mail get its name? http://www.templetons.com/brad/spamterm.html |

You cannot use simply any burning program because the decrypted data is not stored as a file on disk. 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. -- Jeff Rife | Sam: What d'ya say to a beer, Normie? For address harvesters: | | Norm: Hi, sailor...new in town? | | |

So what? This way works just fine and I can do it now without hacking the TiVo. 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. -- Visit Burning Man 2002 in my photojournals http://www.templetons.com/brad/photo/bm02 |

[snip] It's been implied here that ReplayTV does store in a standard MPEG2 format. Well, at least one that is somehow easier to use when extracting the video from the drive directly. What's going on there? Does TiVo seek/search recorded material faster than ReplayTV? |

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. -- Spam was 25 years old in May of 2003 -- read more http://www.templetons.com/brad/spam/spam25.html |

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. Sure...real time. But a half hour show is only 22 minutes. And if it's a half hour show on MTV, it's more like 15 minutes. So real time...big deal! 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. Sure, but I am not a pirate. I still pay for my music at the store on CD's and the DVD I made is only for myself. I'll probably even buy a copy of the shows I made if they ever come out on DVD. I must be one of the few people left who believe in supporting things I like. 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. I doubt this will ever happen. Maybe with digital TV but not for analog. Analog is dead anyway. 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! |

One type of dongle that gets a lot of use is the HU cards in satellite receivers. 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. -- Spam was 25 years old in May of 2003 -- read more http://www.templetons.com/brad/spam/spam25.html |
