My DOA3 CD is pretty screwed up....I don't know what happened, but over the course of a few hours the game started to stutter during the FMV finales for Hitomi(the runaway Shinobi). I assumed it was because I didn't clean the CD, so I cleaned it with a cloth...didn't work. I then went out and got a CD Scratch Repair kit and used it on the CD(SkipDr), and it also didn't work. I used that Scratch repair kit 3 to 4 times on that CD, and it didn't do squat. I called Microsoft, and they assured me that since my other games worked great, it wasn't the fault of the XBOX. So now what should I do? go out and buy a new copy? (I purchased the game January 18th from an online retailer, www.dragon.ca)...suggestions?
