For the video encoder (wmvencod.dll) released with Windows XP and Windows Vista, this property should be set to 1, 2, or 4. Other values will be rounded down.
For the video encoder (wmvencod.dll) released with Windows 7, this property should be set to 1, 2, 4, or 8. Other values will be rounded down.
