I just spent considerable time installing and testing ReClock under Vista Ult. SP1.
Except that it doesn't work with PowerDVD, nor with [that unbelievable bugfest called] Arcsoft Total tra-la-la and that EVR is the only renderer with which I can get DXVA for 1080p H.264/VC-1 to work in MPC HT (and as you rightly say, ReClock don't do EVR).
So what exactly do you mean with "works just fine under Vista"?
S.
Reclock doesn't really work properly with DXVA enabled. It can't perform it's Vsync properly.
May I ask why you need DXVA? Basically any dual core processor will do it in software. I have an old Opteron 165 and it does full software decoding easily.
