Ok I have a slightly odd problem... I was playing on my box earlier and everything is fine.... I have a few backups on my HD and they still work just fine.. Video and sound are perfect... I put in a couple of other games that I have and can only hear the sound of the game and see no video...??? Any ideas what this one could be? I do have High Def cables, but it didn't cause any problems yet!!! Please let me know what I can possibly do...?? Would it be settings if a game doesn't support High Def?
