thank you for your advice anyway.
I've just been playing around on lucid minimal. all i have installed is the bare minimum (for me) to run xbmc,
i installed ssh
installed nvidia 256 drivers
lbvpau
xbmc-live
and rebooted. i get the judder, and it is once per second. i timed for 11 jumps, and it was 11.87 seconds (accounting for .25 seconds to start and 0.25 seconds to stop it's near as damnit 1 per second).
I need to determine whats doing it, some kind of clock or process which is repeating something once per second. This may now be completely off topic.
Any ideas?
edit - i just checked my kernel log, and can't see anything there (nothing which is once per second).
