I was sent a new box after a RRoD. The new xbox will play more recent games (MK9/UFC 10) but when i use older games (GTA4/SW:FU/CoD) i will get the "Disc region code unreadable" message. Says same message with all DVDs. I also noticed that the new xbox they sent me did not have an HDMI output which sucked. Anyone have any similar issues or know whats wrong with this?
