I tried TinyVista, but the MCE Remote didn't function so I had to revert to my full Vista install. I just recently upgraded from XP and I'm quite satisfied with it. My Athlon 2.4 ghz and 2 gig ram cope very well, and now EVR is on, my performance is actually much better due to hardware DXVA! Especially menus in StreamedMP are running smooth unlike under XP. Just trim down the Vista features and you won't regret it
