Hi,

I've been trying to backup SnowWhite R2. I've demuxed 2 audio tracks and the video stream from VTS_01. I've already figured out to skip the last chapter (wich gives inconsistent bitrate errors in Maestro while importing).

When I import the audio streams and video stream in Maestro, the video is 1:00:20 and both audio streams are 1:20:00. I've tried DVD decrypter, DVD2DVD-R and Vobedit for demuxing but they all give the same result.

I have seen some posts about SnowWhite on Doom9, but no one seems to have the problem I have.

Did anyone has the same problems I've had, and how did you solve it?

Thanx in advance!

Weirder problem with Jungle Book! When I import the videostream in Maestro, it displays 14 seconds, while the .m2v file is over 4GB!

About the last part (14 seconds) - this is one of the problems with simple demuxing. A vob can contain more than one video stream, I'm not talking about interleaving now, but sequentially. This is because the vob files hold all the video assets for all the titles in that title set (VTS). Each seperate title can (and should) have an End of Sequence header marking the end. Most likely you got a very short (logo maybe) video prior to the main feature in there. Get rid of it by first selecting the cells you need. For starters, just eliminate whatever the first cell is.

Come to think of it, this is probably the first problem as well, 20 minutes of trailers either before or after the main feature.

The m2v file from Jungle Book contains the entire movie when i play it in Mediaplayer! Only when Maestro imports it, the duration is 14 seconds...

Benza, when you play it, is there any "animated logo" or something like that before the movie ? If so, time it and you may see it lasts 14 seconds. I think that's what ARky was referring to. You'll have to
get rid of the corresponding cell before processing.

Solved!

I used DVD2DVD-R (1.37), unchecked last chapter (wich is the Disney "protection") and checked "force re-encode" with CBR. After all is done, the new m2v file was about 600MB bigger than the old one. Imported it in Maestro and the movie is the same length as the audio!

I'm checking JungleBook at the moment. I'll keep you posted!

JungleBook also works! Same solution as SnowWhite!
