OK, I found the 11 bits, it worked perfectly. I'll just test for that, and if it's an mp3 I'll feed it into rvf_mux, if not I'll encode with LAME then feed it in. The interesting thing is that the mp3 with wav header works in rvf_mux. I haven't looked at the source code so I don't know why, but I've converted a couple movies that have mp3 audio, extracted with avi2wav, then just fed the "wav"(that's actually an mp3) into rvf_mux and it works like a charm. I haven't seen the source so I don't know why, but it does. So that makes it 100 times easier because I don't even have to bother stripping the wav header off the mp3 because it works with it on. Weird. Thank you so much for your help, I never would have figured it out on my own.
