- sync ffmpeg to cvs (sorry Mike it still doesn't decode your teststream --
something must be broken at ffmpeg, also happens with mplayer)
- added priority sorted lists, now autoprobing should work again.
- fixed infinite loop in plugin loader.
obs: latest ffmpeg contains ppc optimizations, someone will have to enable these
though.
