So i can get my main menu screen, internet browser to project a picture in 1080i, but when i go to play a game it will load the playstation logo the games logo stuff then goes to fuzzy lines, anyone know why?

So i check all that apply, and on the setting in the ps3 menu it says output at 1080i, when un check 1080i it cuts my screen in two down the middle.If i leave all checked as u say i can look around in themenu and the pic looks better but when i go to play a game the pic goes blank almost blank with fuzzy lines, Im loosing hope with this. i know my tv can project a game fine cause when i hook up my xbox it works fine in hd picture.
