Those aren't the results I'm getting. I'm able to play the clip smoothly,
but not with MPlayer, nor can I get good results with it when transcoding
with MEncoder using methods that often provide good results from similar
sources. Could you tell me your SVN version? Can you think of anything else
related to build or configuration that might provide a clue as to why VLC
works perfectly for me yet MPlayer puts a big skip right in the middle of
the passage? I've isolated the passage because to me it seems revealing. The
same thing happens at the same point if I extract a longer clip that
includes the same passage, and this is not the only place where such a
stutter occurs (they occur frequently, but not in any pattern that I can
discern). Thanks.
