i use a decompress prog to decompress ac3 audio in avi's to the pcm format. When the stream is 384 kbit/s or more, it will decompress with no problem, but when i want to decompress an avi with less than 384..it wont work. So therefore i try to decompress it using virtualdub but that still wont decompress it to pcm. Anyone know of another prog or way i can decompress avi's less than 384 kbit/s to pcm format. Thanks

try http://www.doom9.org there you will find everything you need including good "howto's". i personally use besweet for most audio transcoding needs.

Virtualdubmod.
www.doom9.org has it.
