Here's my problem. I first tried to capture the WAV file from an AVI with VirtualDub. I got the "No Audio decompressor could be found to decompress the source audio format." error. After this, i used AVI2WAV to get the wav file. I put the Wav on top of the AVI file and the problem i had was that after converting to MPEG in TMPGenc with the avi and wav, the audio was choppy in the MPEG. Any suggestions. I'm thinking it might be because the AVI already had sound... would this be possible? Any help would be appreciated. Thanks!
