problems with latest flash and a video.

I'm having a problem with the latest flash version and videos on a site called Gametrailers.com.

Playing the Mafia 2 review for pc in standard quality 3/4 of the way through my cpu shoots up to near 100% usage and the video starts stuttering even when the video has finished or paused the cpu usage stays at near a 100%, only closing the page makes it go back to 0% usage.

I don't know if it's meant too, but I checked my gpu usage and it's not using that. (2% usage)

I tried un-ticking hw acceleration and it still did it. I should mention that so far it hasn't done this on youtube it's just watching videos on this particular site.

win 7 home prem

E6600 core 2 duo at stock

2gb ram

8800 gts 640mb-stock-latest drivers re-installed.

I've also re-installed firefox and latest flash, oh and it did the same thing in Chrome as well.

In the pic below you can see the video in standard quality has finished downloading and is paused, at this point it was stuttering and unwatchable.

I've benchmarked my cpu and gpu and don't believe it's my system as I have no problem when gaming.
