Fwiw, I never had that problem on my MBP running windows with 720p video and it's just a 2.6ghz core 2 duo with a 8600m (also Win 7 x64). I never tried 1080p iTunes video, though I know the machine is perfectly capable of decoding 1080p mkv with xbmc (in either Mac OS or Windows). I will agree that iTunes sucks unbelievably on windows compared to Mac OS, but I have had the problems you experienced. If it's still a huge issue with you, you could decrypt all your iTunes video content and play it back using something else (xbmc, perhaps, which uses DXVA). I ended up doing this to leave the Apple ecosystem for good, but that was for unrelated reasons.
