mine does this.... think the chips locked

put a movie dvd in then boot up,
it takes you to the browser screen and shows the movie disc and mem card,
eject that disc and put the game in,
should now start the game automatic.

try it a few time if it doesn't work first time, always make sure you unplug the ps2 at the wall for approx 30sec before you try again.

hope this works....
