Problems with my DC

heh, let me rephrase what I was trying to say. I was in a rush typing it last time. What I meant was when I first burned Crazy-Taxi 2 and Stunt GP they worked fine, but after the first few times it ####ted not wanting to recognize the disc, and when it did pick up the disc and finally ####ted the game it would ####t reseting in the middle of gameplay. Now when I try to play them it wont pick up the disc. It says please insert Game Disc. I thought it may have been my cd's so I went out a bought a better but it gives me the same results.
