The ColorKey property sets or retrieves the color key used in closed captioning.
[ iColorKey = ] MSWebDVD.ColorKey
Returns an integer value representing the color to use as a transparent background for closed-captioned text. The default value in 256 colors is magenta, and off-black in any other color depth.
This property is read/write. This property applies only to the closed-captions, if any exist, not to the subpicture stream.
