To say win2k8 is faster than Vista and that's the only reason you use it is full of crap. Search teh net. You could make Vista as fast as 2k8. Besides, there are drivers that are not available on 2k8 but are avail. on Vista. Turn off Aero on Vista then you will have 2k8

Totally agree. Building a box like that and could keep it running quietly like a regular DVR is not cheap. Like other poster mentioned, popcornhour is the way to go. Simple and affordable.
