Did you get a warning about VBR audio telling you that it would be out of sync?

Seriously. You get a warning that your audio will be out of sync. Then it is and you wonder why? Since you are converting anyway, just set the audio to full processing and it will get decoded to pcm.

probably a warning that it will create skew.

change the audio to a .WAV file using Virtualdub. Load the file. Go to "video">Direct stream copy. Under "audio">full processing mode, Click "audio" again. click Conversion check 48,000Hz and check "high quality" and ok. Go to "audio" >compression, select "no compression" (PCM) and ok. Finally go to FILE> save WAV. this will produce a .wav file (audio only).


when its done, load the original avi file again under file. go under audio, select full processing mode, go to audio again, select wav audio. load the wav file you made earler.

under video select direct stream copy, under audio, "full processing mode">compression>i use LAMEmp3 CBR>file>save as avi.
