Hi!
Since now I haven't been encoding myself much (only few SVHS rips according to guides here at doom9.org). Took some time until I figured all the things out but at the end everything worked as expected (and described in the guides).
Now I want to do another thing. I have a DVD with Bruce Lee's Chinese Connection movie (NTSC with AC3 stereo) and want to create 2CD DivX. Here's what I did:
1. Ripped the main movie with DVDDecrypter in File mode into single IFO/VOB pair. If I play this ripped movie in WinDVD or open it in XMpeg everything is OK.
2. Opened the VOB in VirtualDubMod (latest version with update applied). Went for 2-pass DivX encode, with MP3 at 64kBit/s, 48000Hz Mono. What I got is absolutely out of sync. Even when I play the input file (VOB) in VirtualDubMod the audio and video is out of sync (quite strange).
I let VirtualDubMod save the audio from VOB into WAV (did also the same with XMpeg) and got audio file that is 1:46:28,731s long. Strange enough the video file itself is 1:25:34,463s long with framerate 29,970 (153880 frames). So I tried adjusting the framerate in output DivX - couldn't fix it. At the beginning it works somehow but it progressively gets outof sync. I got the same result with saving AC3 stream.
What could be the reason? I suspect the different length of audio and video tracks could do it. But why? What am I doing worng?
This maybe is a very newbie question but believe me, I tried searching this place, VirtualDubMod forumj and some other and couldn't find the answer. The only thing that looks similar are these 2 posts (byt they deal with capture and this is DVD rip - or can it be a VFR on DVD???):

Thanx a lot...
Some update: When I open the movie in XMpeg it shows that it has got the framerate NTSC 29,970 but also says detected FILM: 23,973 (or something like that - setting FR at this value doesn't help also). Anyway if I divide number of frames with number of seconds I get something like 24,09 (which doesn't work also).... Anyone???
Update update: After better searching I found these articles here:
http://www.doom9.org/ivtc-tut.htm
http://www.doom9.org/mpg/dvd2avi.htm
http://www.doom9.org/synch.htm
Can someone please confirm that these articles describe my problem? Is that where the problems lie?
