I have that issue.(there are many others as well)
The issue is with the dashboard. I cannot launch any xport emu's with 480p enabled in either xbmc or unleashx. If i do, I get the same screen as youurs. I installed evox (old reliable - if you will), and launch my emus from there.
Another option would be to diable the 480p in your dash before launching. But then you cannot enable 480p within the emu, as it is not enabled within the dash.
My solution was to Launch once with evox, set all to 480p, then launch with unleashx and xbmc with the 480p diabaled. The emu will still start with the 480p enabled.
I am uncertain if this is just a xbox version 1.6 issue (this is what I have)
Note: evox is a dashboard (an old oudated one). Can be located in the usual places. Simply install it as an app withing your current dash.
Note: For more info, use the search. The goolge search will still pull up information on this if you use the right key terms - eg 480p xport, etc
I have not heard of any issues with the 1080i enabled, but that causes slowdown on my dashes.
