I have a near perfect GBPVR solution currently running on Vista Ultimate 64 - I say near as all mpeg2 is perfect (smooth as silk news tickers etc) however H264 1080i is problematic. I can only get acceptably smooth performance on pans for sport (mostly soccer) using the PDVD H264 codecs and while these can be 100% perfect, every so often they stutter (where it looks like bad deinterlacing or every other frame is being dropped. Hard to explain but the same is true for 7.3, 8 and 9). It will playback perfectly for X minutes (where X can be anywhere from 0.5 to 30 or so) then ~5 seconds of stutter, then it can right itself for another X mins (or it might stutter until I get annoyed, exit PVRX2, restart and then I'm back to perfect for a while). The fact that it's fine after I exit the app and restart make me think something funny is going on in windows but I cant see anything running that would cause the problem. The CPU us always ~5%, I changed the on board HD3200 to a HD4660 so that has enough power... Memory is Dual Channel DDR2 1066 so I assume not a problem. I'm wondering if it's DXVA related and thus a Vista issue, an ATI driver issue or a PDVD codec issue...
Anyway the question really is what do people think is the best version of Windows to use for GBPVR? I have someone offering to get me a copy of Win7 and I'm wondering if its implementation of DXVA along with the fact it's not as hungry as Vista might see an improvement. That said, should I try XP for the laugh (I have a legit copy I'm not using elsewhere)? For Win7, does it make a difference if I get home premium or professional? I'm getting a new disk so can play around with XP/Win7 and see without screwing up my Vista installation I guess!
Any advice gratefully received.
