I have these three asf files. I am using virtualdub 1.3c since it will open these asf files. The problem is when I try to save the wav it says "ACM failed to suggest audio decompression format". To me this sounds like I don't have the required audio decompression installed. When I play the clips they work fine, I get both audio and video. What can I do to extract the audio? I also tried dbpoweramp converter and it said something similar. Please help.
