Vista Busines DVD

[TerraPhantm]

Hey, I have Vista Business Edition, and every time I try to play a DVD with WMP, I get error code C00D116A, which states "Windows Media Player cannot play DVD video. You might need to adjust your Windows display settings. Open display settings in Control Panel, and then try lowering your screen resolution and color quality settings."

I've tried reducing my resolution and color quality, as well as downloading several DVD codecs, but I always get the same message. TIA for the help!
