Hi folks. I've had an ATV since the 2nd gen and it has been great. Generally I use it for Netflix, Hulu+, and to feed video from my iMac in the next room. Lately, I have been acquiring more blu-rays with "digital copy." I didn't really care at first but since I had them I figured mise well redeem them while it was available. However, when I go to watch the redemption copy, the ATV3 requires me to log on with Apple ID and password. My question is: if I log in like that, will it require a password again to buy content, or will it just one-click the buy right off my credit card? I ask this because I have three children who use the ATV all the time and who will buy stuff if they are able to, since even good supervision can't be there 100% of the time. (Yes, I'll discipline them if, make that WHEN, they break the no-buying rule... but in the meantime the money is gone. No good.) If it lets a logged-in user buy at will, I guess the redemptions go back to being worthless and I just let the kids stream ripped video from iTunes... Thanks!
