The needs to encode some sound in order for mencoder to work right
does apply only to avi or also to mpeg?
Because resample to 8000 hz 8bit mono pcm does not work if you are 
creating an mpeg (-of mpeg). I imagine that if I have to encode some 
audio in the mpeg, I should use a low freq mp2, isn't it?
