Hey guys!

I jumped aboard the HD-DVD camp this past January when I purchased an XBOX360 add on. Currently its just connected VIA component to a $300 19" Insignia HDTV in my dorm room. Its not a bad little set up

I have one quick question, my HDTV's native resolution is 1480x900 or something to that effect (I know for sure the second number is 900). It's capable of running both 720p and 1080i...which output setting would produce a better image for me? Currently I have it at 720p.
Anywho, my collection:
Ultimate Matrix Collection
King Kong
F&F: Tokyo Drift (Combo)
Children of Men (Combo)
Smokin' Aces (Combo)
Hot Fuzz (Combo)
Fear and Loathing in Las Vegas
Superman Returns (Combo)
Full Metal Jacket

The Last Sammurai
300 (Combo)
Blood Diamond
The Departed (Combo)

Payback: Straight Up
