Very strange - but Netflix used to work with very little problems on my appletv3. After updating to 5.1 - 90% of the time I try to watch it I get an error message saying its not accessible, please try again. On my appletv2 (also on 5.1) - I almost NEVER get the error message. I was using the 3 in the living room to watch kids shows in the morning while I got ready for work, but I've had to swap out the one in the bedroom which is not ideal. Is this part of the weird 'wired Ethernet' issues that have been plaguing 5.1 users?
