Note that the MPAA considers DVDxcopy illegal under the DMCA, and is trying to shut it down. This whole thing about extraction is not that big of a deal. I just ran a few cables from the TiVo over to the computer. Grabbed in what I wanted witha DV/Analaog converter, and made a DVD. Looks fantastic! So it's not the digital file sitting on the TiVo? So what? This way works just fine and I can do it now without hacking the TiVo. |

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 |

To prevent the possibility of a bit-for-bit copy of a retail DVD, DVD-Rs don't support CSS. DVD-Rs aren't recordable on the area of the disc that would be used to store the CSS keys. So, DVD X Copy works by not copying those keys, which then makes the copy completely un-copy-protected? |

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. Video on the TiVo isn't encrypted. It's just stored in a non-standard format (one that allows faster seeking/searching than a standard MPEG-2 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. _/_ Scott Alfter (address in header doesn't receive mail) / v \ send mail to (IIGS( http://alfter.us/ Top-posting! \_^_/ rm -rf /bin/laden What's the most annoying thing on Usenet? -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.3 (Linux) iD8DBQFAAbsFVgTKos01OwkRAjXFAKCT7GwnxyWV03gNtHOejQ bJha9mwQCgn2sp tbDgK02SW/oC5C5G7/1nZyE= =4wsA -----END PGP SIGNATURE----- |

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.

[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? |

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. -- Jeff Rife | "You are now dead.

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 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. Well it sure is easy and still looks quite good. I mean, it's only NTSC TV , not HD or anything. I've seen some purchased DVD's of features that look worse. 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! |
