Ok well thats dumb.I guess I will just use the HDMI wire for my cable and the HD AV wires for my 360.
Well now I'm kind of curious. If you're using component then there shouldn't be any difference between them and HDMI. Unless I'm misunderstanding what you mean by "zoomed out" it sounds like you're using composite cables, which aren't HD.
By zoomed out do you mean everything like text just looks smaller or is there a black border around the image like http://farm4.static.flickr.com/3268/2578640590_648ae19e54_b.jpg?
