Xbox360 Oblivion disc issues...

I have emailed Microsoft a few times (worthless, but still worth a try) and I have read a few forums on various sites to no avail. It is telling me the disc is dirty and needs cleaning, or something along those lines. It happens whether I start a new game or load one, and it always pops the message up halfway through the load. It just up and happened one day, the game had been running fine since I purchased it on release date. Anyone have any ideas? I am not looking for a miracle as I am sure it is not something I can fix, but I just want an explanation to calm my anger.

I have debated playing it on my PC but it is a long game and it is much more relaxing and comfortable playing on the couch on the big screen... damn you Microsoft.

can't you take xbox360 games back to the shop?

Same thing happens to my game only its more random. It usually happens when I interact with somebody then I hear my disc loading really loudly and the game freezes and tells me I have a dirty disc. I'm going to return my game and get another one. I have the 360 version also and yes you should just return urs to where you bought it from....
