I have been playing GTA 4 for several weeks and sudenly out of the blue, when inside the game, a sign saying "the disc is unreadable try cleaning it" apear. I have tried playing it on other X-box 360s but I ́v hade the same problem. A quick look at google gives me the impression that others have had the same problem. Theres even a video on youtube showing it. It seems there is a manufacturing fault. Need help!

Does anyone keep getting and unreadable disc error anytime they try to play. The first two weeks I had the game it worked great and then all of a sudden my 360 can't read it. The game gets through the credits and to the safe house save point. As soon as I start to move Nico around I get the damn unreadable disc error. I go back to my main menu and there it is, GTA4 completely readable in my tray.
I try to start again and I get the same error.
Someone please help me. The store won't take it back cause it is defective and rockstar should replace it. I waited a year for this game, stand in line, pay 60 bucks and now I am screwed.

I have been trying to get past this tedious mission of killing Jimmy P., and it is the worst gaming experience I have had in recent memory. For the love of God, why did you make this mission? I hate it and am considering never playing GTA4 ever again. The helicopter weapons absolutely suck and when it inevitably gets shot down, I have to start the level all over again, and again, and again, ad nauseam. As you can see I am highly annoyed with your creation. How do I get past this nightmare of a level? In my opinion, games should be fun. This is not fun. It is torture.
