There a lots of problems of totally different kinds. For instance this
one (fresh cvs checkout, compiled with Debians' gcc 3.2.3; I'm
bootstrapping 3.3 right now):

libmpeg2 works fine but is almost too slow to play DVDs. Works
find with xine for instance.

Hrm, I wish I would get it going at all because that's where
the real fun started last time I looked (MC misplacing parts of the
picture, IDCT fed with wrong values, chroma and luminance swapped,
etc.). Unfortunately all  video sources I have here (OGG XviD, AVI
DivX3, AVI DivX4, VCD, SVCD, DVD) crash ffmpeg. :/
