hey. just wondering how the downloadable Halo is running? i bought a copy a few months ago and i have to play it on 480p fullscreen because im assuming it's in only fullscreen. it had the vertical black bars on the left and right of the tv. is there a way to fix this in the game other than changing my resolution and aspect? is this problem on the downloadable version as well? or was it just my copy? i got the greatest hits version if that matters.
