Lol no it's not. Why try to correct someone if you have no idea what you're talking about?

@Hey Im Swat 1. Your answer was pedantic. It was irrelevant to the central point of the question, making it "non-responsive." 2. As others have pointed out, your answer is WRONG. I did a bit of digging online and found that XBOX 360 discs are DVD and that XBOX ONE discs are Blu-Ray. 3. The SLIGHT twinge of sarcasm to your basically empty post was entirely within the realm of acceptable response. You took offense at me saying "umm... thanks" -- the implication being that your information was of little to no use -- and it turns out it WAS of no use.

In all fairness, you tried to add your two cents where it wasn't required and you were completely wrong. In fact, Im pretty sure it's neither a CD or a DVD, its a Blu-Ray disc.
