Howdy Just got my 360 and am realy loving it so far! All set up now into my wireless network and working fine apart from ... When playing games (Gears of War and Arcade Live stuff) the picture is flashing which is annoying on the Arcade games, but downright dreadful on GoW...the background is just a mess of coloured flashes. I presume this is not a "feature" of the game is it looks terrible, but do any of you wise-ones know what this could be? Have you seen this kind of behaviour before? Is it a dodgy copy of the game? A dodgy lead? A dodgy setup? For reference, it's attached to my Pioneer PDP434HDE with the standard component cable that it came with, in HD mode. Thanks in advance of any help/pointers.
