Bug Description
I have 3 machines with Intel graphics. Each played HD video including 1080i (the most challenging) well on 8.10.
On 9.04 they are all jumpy. This is independent of the media player (vlc, mythtv, mplayer, totem). It is well known that on this generation of chips (Intel 915, 945, 852 ..), the Xvideo extension works best with the Overlay Video (rather than textured).
xvinfo shows that I am using Overlay on 9.04 as I did on 8.10.
I also tried reverting to the 2.4 Intel driver as in

and that did not help. Most of the people reporting relief on that page refer to issues involving graphics, not HD video.
Note, I do not have compoz turned on. Another clue is that Xorg shows a high cpu utilization, higher than than the media player itslef.
