having same problem, factory reset DID NOT fix it.
once i start Netflix it hits the second bar on the Netflix startup and give me the netflic.com/tvhelp link, hitting the hme button, back etc does nothing. the only thing i can do i turn off the box, turn it on, and rinse and repeat until it finally works, usually its taking me 4-6x doing this for it to work, you guys need to fix this problem asap
