Hardware Accelerated Video not working in 10.6.7

Question

Hi,
I have had a problem with my 17" i7 Macbook Pro for a while now, and have been unable to find any information on it. When attempting to play H.264 videos, I get the following error messages in the Console:
30/04/2011 15:48:53 /Users/adnium/Desktop/WebKit.app/Contents/Frameworks/10.6/WebKit.framework/WebK itPluginHost.app/Contents/MacOS/WebKitPluginHost[14717] ava error: /SourceCache/AppleVA/AppleVA-4.10.23/Framework/VP3CoreMediaInterface/AVAFVP3Cor eMedia.c: IOAccelFindAccelerator failed for display number 3, error = 3758097084 [entry = 9303, did = 3f003f, service = 0, fbIdx = 0]

I should point out that this error appears any time I use an application which uses hardware accelerated video, including Quicktime X, Safari/Webkit, etc. I have searched around for solutions to this problem, but haven't been able to find anything.
Using internal/external display makes no difference either.
So far, I have tried re-installing 10.6.7 using the Combined Updater; repairing disk permissions; using various different browsers; uninstalling Perian; and waving a stick over the Mac. None seem to have solved this issue, and I'm beginning to suspect this is a hardware problem.
Does anyone know how I can fix this without sending it in to Apple?
Thanks for your help.

Ah yes, when you waved the stick over the Mac, you didn't tap three times on the monitor!
Ok, kidding aside, you did backup your data right? Should do so because the next step is likely a bit risky.
So you did reinstall OS X fresh, from the installer disks and then updated? Same problem? Right? ok.
Have you turned off integrated graphics in the Energy savings panel yet? this forces the use of hardware graphics.
Does it only occur in Safari, iTunes and Chrome?, cause all these are based upon the *cough* (insecure) webkit foundation. Perhaps Apple had to turn off somethings, perhaps that's reporting the errors.
Alas, if your using Firefox are you having any issues?
