Recently I went from Ubuntu 9.10 (Karmic) to 10.04 (Lucid) on a Pentium
M / Intel 855GME laptop, and the Xvideo performance significantly got
worse, Both can handle 720P, but karmic can handle 1080 and Lucid can't.
On the 1080 video on Karmic I see Xorg at 12% of the cpu with 20% idle
On the 1080 video on Lucid I see Xorg at 38% of the cpu with 0% idle and
it can't keep up.
In both cases xvinfo says I'm using the X-Video Extension with Video
Here are links to the Xorg.logs, in case anyone can see what changed
