You're probably getting some loss due to the analog nature of your componenet setup and that's smoothing out the jaggies, just a guess.
I'd set the xbox 360 to 1080p if it were mine.
Edit: to clarity, I'm also using the xbox 360 HD-DVD addon so I leave it on 1080p all the time and don't worry with it. If I was using games only I'd probably leave it on 720p since most gaming content is just that.
