For some reason, I cannot play a DVD in Window Media Player while using the ATI graphics. I get an error that says something like, "WMP cannot play DVD because the codec, graphics driver, digital copy protection, etc. are not compatible. You can try to update your graphics driver... blah blah blah" I updated to the latest ATI driver from their website, but I still get the same error.
I tried downloading another player, but that didn't work either. Any suggestions?
