This setup is highly unlikely to work well unless your "AMD 2.0 Ghz"
is a dual core.  I strongly recommend at least an x2 3800.  X and Myth
are both extremely busy, and if you are outputting to 720p and playing
1080i content, you will want to use Bob 2x deinterlacing - which is
quite CPU intensive.

I had a 3500+ which _almost_ was fast enough, but there were still
enough frame drops to make 60 fps content too annoying to watch.
Moving to an x2 3800 cleared up the problem.
