I have an AVI file. This file, when opened in VirtualDub shows an unknown audio codec and won't decompress. When opened in TMPGEnc shows no audio stream. When I open it in Media player it shows the audio stream as Morgan Stream Switcher.
Obviously this isn't going to work for converting to VCD. I have tried using the decompresser in AVI2VCD and that won't decompress it. Any suggestions on how to get the audio stream on this avi file converted to any supported format for VirtualDub, or extracting it into wav format.

Thanks,
