DVD won't play (on my computer)

[TomTheBomb]

i was in the middle of watching a movie on my computer (using PowerDVD) and all the sudden it freezes, so i closed it tried to open it back up and it says:

Error Code: F4D41436
The TV Out port of your display card is not working properly.

then when you click detailed it says:

This copy protected disc can not be played when the TV out function is enabled.

i've watched lots of movies on my computer and i've never had this problem before. Whats going on??

i tried playing it in InterActual and it says:

Error PL4010: A Macrovision® error occurred while trying to play the DVD. Your current display driver may not support Macrovision® protected DVD video, or you may be using a display mode not supported by your system. Please refer to your video hardware manufacturer for information about Macrovision® support.

another thing, i just installed service pack 2

Older video cards with TV-out have some kind of copy-protection, not enabling TV-out when playing DVDs (just to prevent copying it to VHS). Newer cards have a Macrovision chip that produces some non-standard signals to mess up the image in video recorders.
I think something happened to this protection. Maybe the Macrovision chip is no longer recognized. Try to reinstall the video cards drivers.
