Alright, here's the situation. I've located my dvd player on my system. And yes I have a DVD disc drive. None of my hardware has changed. Only my OS has changed. For some stupid reason my disc drive won't even recognize that I have a DVD in it. What used to happen is that if I put a DVD in the tower the DVD player would start up on its own. Now it not only doesn't start up, but it won't recognize that I have a DVD in the disc drive. If I push play on the player it says "Supported Disc Not Available". What is going on?
