dvd player

I recently installed Heavy Metal and now my dvd-rom doesnt play movies I have a ati rage pro xpert@work card. Could the gl function have voided out something on the card when i downloaded the gam any help and suggestions would be welcome.
thanks

I had the same trouble with the Creative DVD-player. I found if I uninstall open gl then I can play the DVD again. However, this can be a real pain in the A** when you want to do both play the Heavy Metal and your DVD...
Let me know if U find anything out ---> Please! Thanx...
