Fixing "corrupt files" where audio cuts out??

[Questmark]

Hi,
I have an avi file, and I'm having some problems with the audio.

I could play the file fine. I now want to burn it to a DVD (which I've done before for other files many times). When I tried to encode it, the audio started too soon, and was out of sync. When I went to demux it in VDub Mod, I found out that the audio file had "improper VBR audio encoding." I then went through the process of re-encoding it in Winamp (following a thread's instructions) in order to make it an appropriately encoded CBR audio file. This seems to have worked. I can now load it in VDub Mod (which it wouldn't even let me do before). However, when I go to save the new combined file, I'm told that "audio samples 56832000-56896674 could not be read in the source. The file may be corrupted." I tried running the video through the error check process on VDub Mod, but it didn't find any errors. I also tried simply running the new audio and the demuxed video through tmpgenc, to just see if I could enode them to an mpeg2. The process seems to have begun fine-- the audio was in sync, etc.-- however, the audio cuts out completely about 20 mins into the completed mpeg2 video. It stays synced the whole time it's playing, so that's not the problem. It simply cuts out part way through.

The video is an Xvid file, and the audio was originally an MP3 with this info--
127 kb/s (63/ch, stereo) VBR,44100 Hz.

The audio I re-encoded with winamp is now a .wav file, and has this info-- 1536 kbps, 16bit, 2 channels (stereo), 48kHz, PCM.

I simply want to encode this to an mpeg2 and burn a DVD, but I'm kind of stuck about what I should do with the audio. Or is the video somehow the problem? I've searched, but I haven't been able to find anything to solve this problem. Help would really be appreciated. Thanks.

Instead of demuxing it, I would save it out as a WAV in VDMod, using full audio processing. Then use that to convert to MP3 CBR in VDMod again. But if you are encoding it through TMPGEnc to MPEG, just use the WAV file that you extracted with VDMod as the audio source and the original video as the video source. This seems a lot simpler. It may not solve your audio problems, but it works for me.
