below and will automatically be adjusted if it is too low. A too high value may cause

memory problems on the Matrox board. Default value is 6.

• Streaming Size: Not in use.

• Texturemanager Size: Defines the size of the texture buffer in frames. Default

value is 8.

• Video Delay DVE: Sets the number of frames the live input should be delayed

before it can be used as a DVE layer. Default value is 0 (Off).

before it can be used as a texture in the scene. Default value is 4.

value is 0 (Off). The minimum VBI values are (as for VideoOut):

• NTSC: 7
