Well, I'm fed up with the freezing problem playing hi-def disks using Vista 64, PowerDVD is not even tested with 64 and nVidia needs their ass kicking, jeez how long do they need to provide decent drivers. I spent alot of money on my HTPC and just want it working without freezing. So it looks like I'm gonna have to change to a different OS. I'm not particularly bothered about MCE as I prefer the simplicity of iMedian MC. I'm tempted to use Vista 32 as I do like the Vista UI, what's the driver situation like with Vista 32? I see nvidia is still on beta drivers, this puts me off as getting decent video colours on 64 is near immpossible. What are you guys using?
