I don't know what it is about this game but it flat out refuses to play on my 360. The first copy of the game was a bit scratched up, but would play until about two weeks ago. From that point on the Dashboard would say "open tray" when the game was in or it would give me the generic message "to put this disc in an X-box 360 console" as if the 360 was some run of the mill DVD player. After repeatedly getting this message despite getting the disc rebuffed, I bought a second used copy of Rainbow Six Vegas and I got the same messages. I got the second disc rebuffed and it would actually play . . . for a little while. Tricky part is I can't just boot up the 360 and pop it in or I would get the stupid DVD message again. I had to play another game first for a little bit and pop it in. Then it would start playing, after playing about an hour or two the disc would go kaput on me. I'm not sure it's the 360 itself since all my other games, including a scratched up 3 year old copy of Halo 2 can still play on the 360. I'm getting frustrated and it's a damn shame since I really like this game. I don't want to buy a brand new copy especially if it's going to end up giving me the same problems. So, suggestions, anybody?
