This topic is old, but this is new to me. I purchased a second hand collectors edition of Lost Planet from my local. I got them to load up single player on the stores console, it worked perfect. Get home and I get the "Please put disc in a xbox 360 console" as stated by an xbox 360 console. So I tried again and again until finally I worked out a quick fix that will wear out the DVD eject mechanisms twice as fast:
1. Put disc in and wait for the white screen of xbox 360 mayhem.
2. Eject disc and as soon as it pops out re-inject with the eject button.
3. Game should load, hopefully.
4. (optional) Remove DVD drive, throw in a fire after pissing on it, then curse microsoft for selling you a crap DVD drive when others who paid the same get different brand and better read ability.
Hope this helps anyone else having this problem. I do think the problem relates to poor disc surface (even slight scratches) and the poor read ability of laser in the DVD drive, which may be one of 3 (or more) brands of drive. That store console I mentioned, obviouly has a decent drive in it.
When I rang the store they said they would clean the disc and see if loads in their Xbox 360, which I already know it does without problems. They said they would not refund because they have the opinion that I may have pirated the game. Well if I had not have gotten it to work using the method mentioned above, I would have scrathed it with a nail, ran over it a couple of times, shat in the dvd case and then got them to load it on their console!
