- Flags
DDVPCAPS_AUTOFLIP

This is useful in avoiding tearing. Flips will occur on every second VREF when the data is being interleaved in memory.
DDVPCAPS_COLORCONTROL
Support for color control operations being performed on incoming data before it is written to the frame buffer is available.
DDVPCAPS_INTERLACED
Support for interlaced video is available.
DDVPCAPS_NONINTERLACED
Support for non interlaced video is available.
DDVPCAPS_OVERSAMPLEDVBI
Support for formats or widths of VBI data that are different to those of the regular video data is available.
DDVPCAPS_READBACKFIELD
Support for the use of TDx_DrawVideoPort::GetFieldPolarity() is available.
DDVPCAPS_READBACKLINE
Support for the use of TDx_DrawVideoPort::GetVideoLine() is available.
DDVPCAPS_SHAREABLE
Support for two genlocked video streams sharing the video port with one stream using even fields and the other using odd fields is available.
Separate properties such as address, scaling, cropping, etc, are maintained for both fields.
DDVPCAPS_SKIPEVENFIELDS
Support for automatically discarding the even fields of a video signal is available.
DDVPCAPS_SKIPODDFIELDS
Support for automatically discarding the odd fields of a video signal is available.
DDVPCAPS_SYNCMASTER
Support for driving the display refresh rate with the video port sync rate is available.
DDVPCAPS_SYSTEMMEMORY
Support for writing to system memory surfaces is available.
DDVPCAPS_VBIANDVIDEOINDEPENDENT
Support for controlling the VBI and video portions of a video stream with independent processes is available.
DDVPCAPS_VBISURFACE
