i have a avi file that im trying to compress but when i go to save avi as in virtual dub i recieve an error message saying error initializing audio stream compression the requested conversion is not not possible.

under video/audio i have full processing mode selected
under video compression i have selected divix codec 4.12
under audio compression i have selected lame 44100hz, 192kbps, cbr 24kb/s.

btw this i downloaded this file off the net as mpeg, but when i tried to open it in virtualdub it would say it can't open asf format so i renamed the file to asf then used asf tools to convert it to avi. under the audio tab conversion and i selected sampling rate as 44100hz & it would work but the file was going to be like 16524.43mb lol
