DESCRIPTION

       Output Matrox card video to television. PAL 50Hz and NTSC 59.94Hz are supported,  Composite  and  S-Video
       output.

       Contains  two  demo programs, normal and swapped. First selects CRTC1 on first output and CRTC2 on second
       one. Swapped connects CRTC1 to secondary head and CRTC2 to primary head. You can use  these  programs  if
       you need text mode or 8bpp mode on TV, as CRTC2 is incapable of these modes.

       In  program  call,  If  VALUE is specified, set the specified option to VALUE. If VALUE is not specified,
       retrieve the value of the specified option.
