I posted this in another forum and thought I would cover all my bases so any info would be appreciated!!!! OK... I've had my DC for about a week. My library consists of: Sonic Adventure Crazy Taxi Virtual Tennis NFL Blitz 2001 Ready 2 Rumble 2 Yesterday I continued my Sonic Adventure game, I can't recall how long I was playing for but all of a sudden I heard a weird noise coming out of the DC kinda like a harsh noise coming from the disk or disk spinner. It did not affect game play whatsoever. It went on and off for the remainder of my play. I killed the power and started again with no problems. Today same thing, harsh noise! It only happens with Sonic, usually when I am trying to kill a foe or into heavy action. I have played all my other games and they play great! I was wondering if anyone has experienced the same problem and could it be the game or console. I have only had it for a week so I would have no problems returning it. Thanks!!!
