I thought that the goal is to prefer ffmpeg to libmpeg2.  It seems
that thanks to Michael, the mpeg2 decoder of ffmpeg is now better than
libmpeg2, especially its error resilience, which is critical when you
have to deal with mpeg broadcast.  I agree that this buffer age thing
sucks in G1, and what I do in filmdint works more by accident than by
design.  I'm just trying to deal with what we have in G1.  Anyways,
could you please apply my DR fix?
