I'm not talking about OF's real problem, he noticed that 'some frames
are skipped' in both passes, and this is another problem. It can lead to
very bad encoding of the first seconds.

"cat VTS_01_0.VOB | mencoder -" results in skipped frames in the
beginning, "mencoder VTS_01_0.VOB" doesn't. When encoding multiple
VOB's, this is really annoying. It will be great if this will be fixed
or if it will be able to run "mencoder *VOB".
