XBox Return Protocol. Here is my issue---Lately after about 10 minutes of playing, my Xbox will fuck up and cause my screen to get a greenish tint. I've been told that this is a precursor to RROD, so I called up Xbox and will be sending it in this weekend. My question--what is the protocol for buying a returning Xbox's? I want to buy one while mine is out of commission, but want to make sure I will be able to return it without a problem. Anyone have experience with this and if so, what store?
