Fullscreen video playback performance

[ironlink]

I've recently bought a new computer, and am running into problems with fullscreen playback of the flash video here on rev3.com.
Around 6 frames per second is all I get. High quality, fullscreen on youtube is no problem at all, and every game I've tried to run (GTA IV, Assassin's Creed, etc.) is fine.

Anybody else having similar problems? Let me know if you need additional details.

Specs:
Core i7 920
6GB DDR3
GeForce GTX280
Windows Vista x64
Mozilla Firefox 3.5 Beta 4
Shockwave Flash 10.0.2.54

Edit: Nvidia graphics drivers version 185.85.

While the version of Flash you currently have shouldn't have any performance problems, it wouldn't hurt to try upgrading to the latest one (10.0.22.87 for most platforms):

Crisis averted! Thanks rylab, dunno why I didn't think to check for updates :E
