This patch will enhance the XFree86 4.2.0 Matrox Millennium II driver to support the X video (Xv) extension (extremely useful for playing DVDs and other MPEGs). The extension is implemented as a CPU to Frame Buffer YUV scaling ILOAD. A true overlay was not used because of a Millennium II hardware limitation that would reduce the maximum usable frame buffer to only 4Mb.

Till now these are the supported Cards
Matrox Millennium II PCI (MGA2164W)
Matrox Millennium II AGP (MGA2164W_AGP) (only experimental driver)

Here are some key features of "MatroxMillenniumIIXvextension":
YUV->RGB 4:2:2 (UYUY/YUY2) fully hardware accelerated
YUV->RGB 4:2:0 (YV12/I420) hardware accelerated with software swizzling
Horizontal upscaling up to 8x fully hardware accelerated (HQ linear filter)
Horizontal downscaling up to 4x hardware accelerated with software decimation (HQ linear filter)
Vertical upscaling software linear filtering
Vertical downscaling software decimation (no filtering)
