Apply the attached patch to CVS mplayer. Make sure you update first --
it depends on other patches I've committed over the past few days.

The patch should make mencoder produce files with B-frames and perfect
A-V sync (or, at least, A-V sync that is not affected by the B-frames).

I plan to commit it to CVS tomorrow, so please give the patch a try and
tell me whether or not it works for you.
