I just got banned today too. I have notification prompts turned off, so I don't know if I was banned while playing a game or not. I booted my system, and saw "Connect to Xbox Live", which threw me off, because I normally auto-connect. Tried to connect - failed, did the test, Z: 8015-190D. I was using iXtreme 1.4, on a Hitcahi, 8x version, I had a modified GH2 in my system at the time, but the actual disc passes iXtreme's schemes, and DVDMulleter, so I don't know if that was the cause. I guess it's possible because I was using 8x fw, but I doubt it, since there's already a new 11 page post.
