forget about 1080i output of the xbox. it's just to slow and has too little memory. 720p is all you can hope for and looks alot better than SD DVD's anyway.
make sure that the TV supports 1080p24/30 for smooth playback of HD-DVD and Blu-ray (and future XBMC on Linux?).

I've read that the Connextant video processer on the Xbox can actually only take an input at a maximum of 1024x768, but can output at 720p and 1080i but since the input is at a lower resolution you're not getting 'true' 720p. Though I imagine the 1028x768 image going in is anamorphic and makes fairly efficent use of the available resolution.
Though you're still effectively only getting 85% of the detail at 720p than you would get at 'true' 720p resolution.

@gulikoza:
I had the same problem. You need to change the parameters with advancedsettings.xml.
The concerned fields are:
<slideshow>
<panamount>
<zoomamount>
<blackbarcompensation>
</slideshow>
I don't remember which values need to be set. But the wiki and some tests should allow you to solve this.
Regards,
Eric

I think you just need to set <blackbarcompensation> to "0" but I'm not sure.

I set my XBMC to 1080i and use the Hardware Overlay option in the video settings.
That produce fluid playback at 1080i with no frame drops. The only downside is that I do get a bit of flickering in a horizontal band along the top of the screen from time to time. But I honestly don't even notice it after a while.
For any video that isn't already widescreen I just change to 14:9 using the Enter button on the remote. That seems to reproduce the best looking widescreen playback. 16:9 seems to stretch things a little to much for my taste.
