Cannot view DVD

Greetings.
I used to play DVD's ok, but now I get an error:

Error code: F4D41436
"TheTV Out port of your display card is not working properly"
and under that
"This copy protected disc can not be played when the TV out function is
enabled."

Where do I need to go to disable the TV out function, as I've never used it
(presuming it's the RCA type connector next to the monitor cable of the
graphics card).

Thank you!
B.rgds,
Kevin

**** Update *****
Nevermind folks. I didn't know where to begin except my local Help &
Support, MS knowledgebase, or here, I keyed in the error on a search
engine and found I needed an update from nVidia for my graphics card. Now I
have more controls for my display but more processes as well. The good with
the bad I suppose.
Thanks for looking at this message!
B.rgds,
Kevin
