So I have a small annoying problem, the right and left sides of my screen are well off screen. Is there some way to calibrate what the 360 puts out? As there is no setting on my TV for that is seems, just up and down

There is no adjustment on the 360. Check if your tv has an "auto adjust" function(that is if you're using VGA)

Edit: Sounds to me like it's a overscan issue, since it's both sides that are chopped. Post your tv model, and also look for a overscan option(might be zoom, aspect, or a few others)

It's a Sony KV-30HS420 30" (crt) no option for that via the few basic settings it gives you :/

You need to do a geometry adjustment in the service menu. Its not recomended if you don't know what you are doing, but geometry tweaks like this are fairly straight forward.

Yeah thanks I was just reading up on some of that, Think I'll be reading for a while before I attempt it myself.
