In EvoX's settings, just change the region to either default or NTSC North America. Chances are, if you haven't messed with the settings that it's still at Auto and switching to whatever region the game belongs to, which is why you get either a rolling or stretched grayscale image on your TV. And danielb, modchips aren't required as a soft mod will work just fine. Since he's using EvoX, his Xbox has been modded using either method and will work just fine with PAL games.
