Try recompiling without the xvmc support. Use the plain Xv drivers. Your
system is probably right on the edge performance wise due to the fact that
you use a software encoded ATI card. I had many problems with stuttering
until I got rid of that compile option. 

If that does not fix it, perhaps its time for an upgrade. Switch to a
PVR-250 card or other hardware capture card and lighten the processor load.
