   An error has occurred in your application

   DAC: TI TVP3020

RESOLUTION

 - Contact MATROX Technical Support for an updated Mgs.sys device driver for
   Windows NT 3.51. However, all video device drivers were re-written to run in
   kernel-mode under Windows NT 4.0 and there are no updated drivers available
   from MATROX to correct this problem for Windows NT 4.0 at this time.
