We figured out our UF problem. So if you ever login to
UF and you go to watch a preview or an actual movie
and it kicks you out of UF where you have to log back
in,

All you have to do is UNPLUG the power cord to your
TV and plug it back in. This lets the system reboot
itself and Walah problem solved UF works great now!

We actually had this same problem with Netflix
a few months back and had to do the same thing.
