Yes, it's safe. You don't see many stolen credit card reports with live, right?
Never heard anything about being safe or stolen. Another question, what if I buy a game/video/gold membership then get a new Xbox 360? Can I still move everything to the new hd?
if you get a new xbox then you can transfer the licenses using the drm transfer tool.
hmm never heard of that. Also what if I get a Gold Subscription, can I transfer that too?
You have a ton of questions about the 360. I'd suggest heading over to the official xbox forums moving forward. Chances are your answers are already posted somewhere and it's a ton more active than here. You'll get an answer within minutes over there for any thread you make.
As far as the DRM tool is concerned, it's fairly new (this summer it came out I believe). I haven't used it but you can find out how to use it (if you need to) on the Xbox website.
Most of your questions are common (FAQ's), so a quick google search will come up with an answer faster than us most likely
Cool I'll look more into that DRM. One last question, so since Gold is attach to profiles, can't I just use a friends?
