to Geraldo Palomo, scottieeh, Avid Cut Pro and everybody else interested in this very old thread: I've done my best to explain some possibilities in my entries. Please read them carefully.
Also, let us know which interconnects you are using, because I suspect most of your problems are being caused by those. Have a good look at the connectors on both sides and describe them to us on this thread. Probably you are using some kind of DVI-I to HDMI adapter cable which isn't fully implemented. Try to document about this and the Sony Bravia HDMI input implementation/ pinout.
Here is an interesting link about the DVI port on your Mac:

Keep in touch.
