Xbox360 PSU. Game loading error.

[Greaus]

I'm curious to know if anyone else has had this problem. When starting up the xbox I get a message saying something along the lines of "Insert game into a Xbox 360 system to play". I have to restart the system usually 3-4 times before it will finally read. I was beginning to think my dvd drive was going out, but it only seems to do it on PSU. All other games I have (or had) started 1st time every time.

A lot of people seem to be having troubles with PSU discs when every other game works fine. I would try exchanging the disc somewhere. If that doesn't work...no sure.
