[MPlayer-users] libavformat muxing broken. So now what?

[sean darcy]

I'm trying to transcode realmedia .rmvb to x264 mp4 for playing over 
upnp on a ps3.

mencoder input_movie.rmvb -oac mp3lame -ovc x264 \
-of lavf -o output_file.mp4

But then I get this message:

** MUXER_LAVF 
*****************************************************************
REMEMBER: MEncoder's libavformat muxing is presently broken and can generate
INCORRECT files in the presence of B-frames. Moreover, due to bugs MPlayer
will play these INCORRECT files as if nothing were wrong!
*******************************************************************************
OK, exit.

So if this doesn't work, is there anything that does?
