With my divx movies i have been having problems extracting the wav some WHICH COME UP WITH THE ERROR in virtual dub saying .....will write vbr values to cbr..... What happens is i save the wav file but IT WILL ONLY SAVE A PORTION..... is there another program to do this..... some1 told me nandub BUT where is the option 2 sav the WAV?
nandub - or virtualdubmod should do what you want (I haven't used both for quite a while for audio stuff, I've switched to XviD + HE-AAC audio in matroska container for 1 CD rips...). If you can't decode to .wav just save the mp3 audio stream to a separate (.mp3) file and decode separately to .wav using e.g. lame, MAD, lamedropXPD, foobar2000 + diskwriter etc. Why do you want to decode the audio + save to .wav at all?
