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.
