I was playing a dvd with my install of Feisty (patched to most recent updates), with the latest nvidia drivers installed for my 8800GTS. About a quarter way through the movie the computer froze and kept repeating the same sound of the current scene. It also started flashing the Caps lock and Scroll lock keys. The only way that I could fix this was to reboot.

By the way 3D acceleration was enabled with the latest Restricted Modules.
What the heck caused this?

My system specs are:
P4 3.2Ghz
1 GB DDR2 PC6400 800 mhz OCZ Ram.
Sound blaster Live 5.1(SBO102)
Plextor DVD Burner model PX-755SA (I was using this to play the DVD)
Toshiba DVD-Rom
EVGA 8800 GTS 640 MB

Please help me with this I really want to play DVDs with Wubi and Feisty.
