I'm totally baffled. My friend burned some things onto a DVD-R for me, and I think something went wrong during the burning because the disc would only play on my Philips standalone player (it wouldn't play on a Toshiba or either of my computers). When it does play, there are some chapters that are really choppy too. So I thought I would try to copy some chapters on my computer, and play them from there.
I downloaded DVD Decrypter and AutoGK the other night and successfully ripped chapters from other DVD-Rs I have, and then I inserted this problematic disc (not expecting too much). DVD Decrypter recognized the IFO information--I can see which chapters to select--but when I tried to rip those chapters, I kept getting read errors. This was not exactly surprising since my computer has never been able to play the disc, but just a few minutes ago I tried it a second time.
This time, while DVD Decrypter reported another read error, my computer went through the motions of automatically playing the DVD--meaning it recognized the disc as a DVD for the first time--and then it actually brought up the DVD's menu--something it's never done before in the 10 or 15 times I've tried to play the disc on the computer! It wouldn't play beyond that in Windows Media Player, but then I opened up PowerDVD, and it played on the computer for the very first time (or at least part of it did). I have no way to account for any of this, but it gives me hope that ripping chapters might be possible. Does it mean anything that DVD Decrypter can recognize that there is information on the disc? And--in light of the recent confusing events--is there hope for this DVD-R now that it will actually play (at least every once in a while) on my computer? Any feedback is appreciated.
--Also, I should have been paying more attention when I got the DVD Decrypter read errors, but I think the error messages say "Uncorrectable error" when the computer doesn't recognize the disc, and then something about a "Seek Complete" (I've forgotten the exact wording) when the computer does recognize the disc. Thanks!
