For basic video rendering and no mixing, VMR-9 can be used if your hardware supports it. Otherwise use the old default video renderer. For DVD playback, the Overlay Mixer or VMR-7 are the only two that supports video ports.Technically speaking, VMR-9 has its own CLSID and its own set of interfaces, structures and enumeration types which are not always identical to the corresponding data types for the VMR-7, due to the underlying differences between DirectDraw 7 and Direct3D 9.It seems that my ATI GPU does not support VMR-9 very well, even with the latest Catalyst drivers for XP.In MP, we should be able to fall back to one of these older video renderers if one doesn't work for us.
