In addition to the Comment #0,
I checked that latest trunk becomes the 100% CPU ,and cannot play OGG Video smoothly.

I also checked http://tinyvid.tv/show/1s1om2tflh80q ,
and the OGG video stutters only clicking bookmark menu of Firefox.

Anyway, Chromium3.0.183.0 (17145)can play smoothly and CPU load is only 70%.

100% cpu usage on Firefox process (sound skipping and video choppy) but only whilst browser window is visible.

As soon as browser window is minimized (completely hidden) sound is OK.

Tested with:
XP 32bit SP3
AMD Athlon 64 Processor 3000+ 1.8 GHz 1GB RAM
Firefox 3.5 beta 4

Is there any way to download the .ogg file for the dailymotion video? Or to turn off their controls? I suspect it's their JavaScript controls using a lot of the CPU. It frame skips a lot on my machine whereas comparable sized videos from other sites run fine.
