I got a G-TV box today, hooked it up to my system and everything went to H E double toothpicks! The Cable box gave me the dreaded 'DVI' signal, and the TV said "Incompatible device". The cable box is a Motorola HD/DVR from Charter, the TV is a Bravio, and the the AV reciever is a Yamaha V667. nothing is old, so I don't understand why I an having so much trouble. Everything worked and still does if I take the Goobox out of the equation. Did I just grab a bad one or what?
