GetOutputEnable	Determines whether the video port bus is enabled.
GetTVFormat	Retrieves the current analog video format.
GetVCRHorizontalLocking	Indicates whether the decoder is expecting video from a tape source or a broadcast source.
IsAnalogVideoAvailable	Check if the source filter supports this interface.
SetDefaultFormat	Set the default video format incl. resolution and framerate for a capture device.
SetOutputEnable	Enables or disables the video port bus.
