Comment (by rob.r at plutohome.com):

 I've recently started using Chroma Key OSD, and that works very well for
 me, but doesn't seem to have much effect one way or the other on my
 prebuffering pause problem.

 On my systems, with the SVN version (8696, before xvmc broke, anyway), one
 of two things happens: Either it gets in a good stride and is able to play
 720p video great for a long time, or it struggles, prebuffering pause over
 and over sometimes several times a second.  I can sometimes pause and
 unpause (or do a seek) and it will begin working correctly again.   CPU
 usage is around 35%.  Since there's more problems with 720p than 1080i, I
 think it's more of a synchronization problem, and not a CPU load issue.

 All I'm patching is that one line of code, not enabling the whole
 "FAST_RESTART" warp audio thing.   That tells me that "unpausing" must be
 too latent on my system for some reason.
