I just managed to get 5 patches committed to libmpeg2, 2 more are queued
and I plan to try to get most of our local diff upstream.

I don't see where anybody is being tortured.  Which problems does
libmpeg2 have *in practice*, i.e. watching DVDs?

MPlayer's policy has always been to default to the fastest decoders.  I
have a borderline machine for watching DVDs, I wouldn't like to see
performance degrade.
