I'm trying to connect my 2007 MacBook to my CRT Sony Wega TV. I'm using a mini-dvi to video adapter. It doesn't matter if I use a yellow rca or svideo, the picture on my TV is all black and wavy. I can vaguely make out the picture on my TV, but it's mostly indistinguishable. I've tried changing the resolution settings but nothing fixes the problem. Can anyone help me with this?
