I am trying to compress the audio for a divx avi with the lame enconder mp3 ACM. I think I have installed everything properly (Virtualdub, divx, lame acm) and lame appears correctly as a mp3 sound codec. But when I save the AVI, Virtualdub tells me it can't start the audio compression. What I am doing wrong? What (good) alternative do I have for a mp3 compression codec?

Thanks a lot!
