I am trying to demulitplex Divx/AVI files in Virtual Dub but I keep getting an error message that says 'The requested audio compression is not compatible with the input format. Check that the sampling rate and channel count of the input match those of the requested format.' I have tried several different DivX/AVI files with no luck. When looking at the file information the compression is listed as 'Unknown ( Tag 0055).' Can anyone tell me what I am doing wrong? Thanks!
