I bought a steel case edition copy of good old Lost Planet recently. But when I put the play disc in to install/play, the console starts stuttering and produces the same sound over and over again, as if desperately trying to make progress. Also makes makes a sound similar to knocking on a table really fast with a tiny rivet. While doing that, it also produces the "disc recognized" sound at the same time after a few moments(when the game appears on the screen with the Play Game option). A "Play Game" does appear, but without the picture of the game. When I press play, it gives me the disc unreadable error.
I'm really confused :S The disc has no scratches at all and is perfectly clean.
If it helps, then the XBOX can read the bonus disc without problems, my PC recognized the problematic disc as an XBOX360 disc right away and showed its contents, and every other disc works perfectly on the console.
