Purchases new Apple TV 2 in late January. Easily set up. Streamed video from iTunes fine. With Netflix was slow, kept buffering, even though same content through same wireless network worked flawlessly on iPad and iPhone in exact same location. Eventually stopped working, even after soft and hard reset. Returned to Best Buy and replaced. New unit started out fine, however, asked to update software and I did. Suddenly died after flawless streaming of Netflix. Have done all the resets, etc. Screen shows the usual menus, but curser will not advance and will not respond. Seems highly unlikely that two different units would have the same problem. Perplexing how user error would cause the unit to crash. Anyone have a solution or at very least, an explantation?
