Well I might remind you I am compiling mplayer here and not ffmpeg 
itself, just using ffmpeg's codecs and filters. I have no files that 
use snow. I had never heard of snow other than in ffmpeg and whenever I 
ask people no one knows what it is. To add to that when mplayer 
compiles it always spits out lots of warnings when it hits snow.c I 
personally would prefer to not compile it but mplayer compiles it 
So as I said I have no files which use it so I can't benchmark. I also 
am unsure how to turn on or off the altivec for just snow and not the 
rest of mplayer.
