I just bought a new Philips LCD TV. I want to hook my macbook up to it so I can watch movies. I bought the Dynex mini-DVI to S-video cord. When I plug it in to the mac, the screen on the mac gets larger, but nothing is on the TV. I have tried both Video 1 and Video 2. I have tried selecting the mirror option and no luck. I have searched the web and nothing has been helpful. Can someone please give me some helpful advice????
