Does cacko still use mplayer-atty?

If so the extra speed is because it links in a proprietry lib from intel
that does some of the mpeg 4 stuff in iwmmxt. A lot more than the stock
mplayer does.

Because of the license from Intel I couldnt put this lib in OE.

Ill try and update OE with your newest code tonight.
