Let me guess, your Fox channel? If so, this has been going on for some time.I have noticed the longer time needed to tune to an OTA channel. The first time it happend, I thought, "Oh no, not again". But then the channel popped in. I guess that is better than having to do a complete reset, but it still needs to be worked on.
Also noticed that it no longer stays on my favorites list and I have to put it back every single day. Why do they insist on messing with this?
