I am trying to play a DVD using WINDVD. When I insert the DVD and I press play, I get an error message in windows saying

"WinDVD Application Error
The exception Illegal Instruction
(0xc0000001d) occured in application at location 0x1d1d121d"

I have installed the NEMO codec pack and tried everything else. I've noticed the same error message occurs even when I play a avi or mpeg file.

Please Please Please help
