I have a 36" tube Trinitron. I don't know the model number, but it has AV's /S-Video /Composite / and input #4 has 5 AV colors... HiDef? When i plug my standard HD cables into Input #4, it scrambles the picture, but I set the xbox cables to TV (not HD) on #4, it give me a clean picture. The picture is better than a standard AV input, but worse in some areas... Why is this happening? I've tried switching out xboxes and cables already, is there a way to configure the tv?
