  I actually started trying to use ffmpeg. but:

1. While I've read that ffmpeg now decodes .rmvp ( and I'm using Nov 29 
svn), I couldn't google up a  command line. Anybody have one?

2. libavformat in mplayer is the same libavformat in ffmpeg, right ( svn 
sure thinks so)? So does ffmpeg mp4 muxing work, but not mplayer's?
