Regarding the slowness, I don't think I said "a second" but rather "a
fraction of a second".  Funny thing is that it may not occur right
at the beginning. It might be a second or two into the sequence that
things speed up for a moment and then go back to slow rendering.

Well, I didn't know if this is known or not. I'll go back and learn
how to do a gdb trace.  I hope it's not too time consuming..

Lot's of things in the docs.  Sorry I must have forgotten this.  I
have been all through them when I first started w/ mplayer couple of
months ago.
