I'm using one hard drive for Windows Pro and another for the mpegs. Also no other software installed. Video card is a ATI X1300 pro.
Your processor is more than up to the task. Even a lowly Sempron will do the trick. However your decoder could be the problem. What MPEG decoder are you using? It has to be capable of working with your hardware (video card) to do transport stream decoding. Without it your CPU is hopelessly bogged down, no matter how fast it is. You should also look at your X1300.... seems like it would be up to the task but check it out just to make sure.
