This is with the latest 360 updates (as of March 4th, 2009)
I scoured the media center settings for atleast 3 hours with out finding a single clue. This is probably something really easy to do, (if at all possible) i just cant figure out how. Any help is appreciated!
How do you change the video size on XBOX 360 using Media Center?
If you change your video settings in console settings, you can get the wide screen view you're probably looking for. As far as videos original dimensions, you won't get this on the xbox. It will either run in 16:9 widescreen or 4:3 full screen aspects.
