I sometimes see a slight hesitation (probably means a frame is late.),
especially for HD playback sometimes, but I don't see "flickering". 
For SD playback, I don't see any problem.

When I was using MythBuntu 8.x's fglrx driver, I sometimes saw the
artifact of slower screen update. It seems much better with the
MythBuntu 9.10 + the latest driver from ATI/AMD website.

The default gflrx driver that you can install with MythBuntu 9.1 did not
work at all on mine, while the latest driver does work. Since I don't
have the same hardware as yours, I cannot say which way to go, but if
it's not working for you now, everything to gain with the new driver.

Note that, my video is the onboard graphics.

OTOH, if "ati" driver (that comes with X) works for you, you don't need
the fglrx driver at all.
