Your in for a rough ride with ATI card. New mplayer supposedly works as
far as hardware decoding goes.. I never actually tried, since I settled
a while back with mplayer-mt (an experimental multi-threaded branch) and
let the cpu handle video decoding. Either way, you will have to compile
mplayer from source. Fortunately, that's not really difficult.
apt-get build-dep mplayer should install all the pre-reqs you need.
The guides you see that require several packages installed up updated
manually are really only needed if you are also trying to build a
functional mencoder alongside the new mplayer.
