Here's my situation, come christmas i'm going to upgrade my 5 year old arcade for the slim. I go to my local game exchange and let them test on the xbox to see if it works properly. After an hour they tell me that the disc tray is stuck, so i lost out on £70. I was completely stumped because it had never happened to me before, so i pry the thing open and put a disc in (i know that doesn't sound very wise, but i tried it anyway) I pressed the open button with the disc inside and it worked normally. So, this leaves me confused and curious and i would like to know if anyone has had the same problem and what they did to fix it.
