YUV Mixing Mode
This topic applies to Windows XP Service Pack 2 or later.
In Windows XP Service Pack 2, the VMR supports a mixing mode called YUV mixing mode. This mode is most useful for advanced TV or DVD applications. It trades some of the power of the VMR mixer for better performance on low end graphics hardware that uses a unified memory architecture design. YUV mixing mode is supported on both the VMR-7 and VMR-9.
