Thanks, Carl Eugen.

The problem is not reproducible with MPlayer. MEncoder produces an empty
file. Here's a sample of the source video.

http://dl.dropbox.com/u/42718751/friendoranemone.mp4

Here's the command.

Here's the output.

INCORRECT files in the presence of B-frames. Moreover, due to bugs MPlayer
will play these INCORRECT files as if nothing were wrong!
