I think the problem is that fundamentally, the ATI driver does not 
provide hardware accelerated MPEG-2 playback and your Sempron cannot 
handle the software decoding without choking.  If you had an Nvidia card 
that supported XvMC you could enable that which would activate the 
hardware decoding and probably give you the performance you expect.
