There's no real reason why the buffer should slow anything down though. The
system should only require a small amount of data in the buffer for accurate
playback - no more than a couple of a frames. I suspect the difference is
more likely due to the client/server architecture. mplayer doesn't have a
network layer in the middle of it's playback path.
