On a different note, I played around with trying to fix the problem by 
recompiling the kernel, and after much mucking around, I finally got the 
problem sorted, which I believe was caused by having ACPI comipiled in 
there. Removed it from my kernel and the jerkiness stopped.

The only problem I have now is that, at the very end of a recording, the 
last 5 seconds or so freeze up the frames for about 10 seconds before 
playback stops, which I can easily live with and probably has to have 
something to do with the hardware XvMC decoding.
