Hope someone can shed some light, as I'm having a helluva time trying to figure this one out by myself. (I posted this message in the Vegas Pro Video forum, too - I'm trying hard to cover all the bases.)
I received a PAL DVD from a friend who transferred some PAL VHS tapes to DVD for me. The DVD was recorded in a Panasonic DVD recorder. (My friend is not technically inclined, so this is the best I can get from him.)
I used VOB2MPG to rip the DVD and create a large MEPG-2 file which I dropped into a Vegas 6 Pro PAL DV project. Playback is fine in Vegas - audio and video stay together. The DVD also plays fine in my Philips multi-format DVD player.
Extra info: G-Spot says the MPEG-2 file is DVD "VOB" format, MPEG-2 Program Stream (1 Vid 1 Aud), Sys Bitrate: 10080 kb/s VBR, with AC-3 audio (48 kHz, 256 kb/s). Vegas says the video is MPEG-2 and the audio is MPEG.
In Vegas, I edited the MPEG-2 file to remove commercial breaks and extraneous material. I simply split the file, removed the unwanted material by dragging and shortening the event, and then butted the ends together.
Now here comes the fun part: I rendered separate Xvid video file and AC-3 and MP-3 audio files, then muxed them in both VirtualDub and Avidemux. I got the same results from both tools - the audio started out in sync with the video, then moved ahead of the video up to the point where I made a cut. Immediately after each cut, the sync was restored, but after 15 or 20 minutes the audio had moved a second or two ahead of the video again.
Then I rendered a Sony DV file from Vegas with PAL video and PCM audio. It had the same sync problems. After that, I put the MPEG-2 file from VOB2MPG into DVD Architect (no cuts) and created a new DVD. It played fine in the Philips player - no sync problems!
In the past, I have found sync problems in NTSC DVD's ripped by VOB2MPG. (These weren't necessarily DVD's created by home DVD recorders.) Using DVD Audio Extractor, I was able to create a WAV file that I could drop into Vegas and would keep in sync with the MPEG-2 video. Not so in this case - the DVD Audio Extractor WAV also ran ahead of the video.
Seems to me the problem is in the structure of the MPEG-2 file, or perhaps the DVD files created by the DVD recorder. But SURELY there is a way to render files that will stay in sync, especially since the audio is in sync with the video in Vegas.
Any help in producing video and audio output files that can stay synchronized will be greatly appreciated. Otherwise, my head is going to go through that wall I'm beating against pretty soon...
