Sorry for my ignorance when it comes to this stuff..im learning on the Go. I cannot play any DVD's through my new Vista system as i get this message from Windows Media Player 11 "Windows Media Player cannot play the DVD because a compatible DVD decoder is not installed on your computer" I can't find where I would uninstall Vista Codex so I can replace it with the K-Lite Codex. Help please!!

Start -> Settings -> Control Panel -> Software
