[QUOTE="rtv, post: 362930, member: 12309"] Well I enjoy this :) There's only a small set of "options" the VMR9 rendering has (coders might be interested in [URL="http://msdn.microsoft.com/en-us/library/ms788066(VS.85).aspx"]this[/URL]). The few which are quality related are those offered in the GUI. Of course other apps can "trick" you into another subjective point (like adjusting sharpness, colors or other image [B]manipulation[/B]) but the identical render graph will definately produce the exact same results ;) There are still tons of options here. Some displays e.g. allow to set the correct HDMI mode (which will be a huge increase in contrast). Sorry, I don't like that fact either but as a matter of fact Vista's EVR renderer is superior here. Especially when it comes to high quality DXVA profiles many will only be available with DXVA2 (The quite common Nvidia 8200 onboard GPU for example only does "BOB" deinterlacing when used with XP and a non Phenom). You might want to try "DXVAChecker" to check the details on this. This is hard to validate: 1. you'd need e.g. the graph details of both (making sure DVBV isn't using overlay, etc). 2. some codec settings are stored per application. 3. some stuff might "look" better while in fact it isn't. Many people e.g. will like high quality 5:5 pulldowns more than the raw film. That's just a matter of viewing habbits - and a common point of "24p" frustration. 4. some differences - especially when it comes to deinterlacing - cannot be caught in screenshots properly. That said I hope to see a sophisticated discussion here :) [/QUOTE]
