So, this is new. Sometime in the last week, one of my HR20-700s started tuning to OTA Fox (13-1) whenever it was supposed to tune OTA NBC (5-1). This was true whether selected directly from the guide or when recording from the schedule. My wife was not pleased that we recorded two hours of Fox programming instead of The Celebrity Apprentice. We didn't notice the problem until yesterday. Now, this morning my other HR20-700, which was fine yesterday also started the same thing. Try to tune to 5-1, actually tunes 13-1 instead. It would appears that someone has been incorrectly mucking around with the OTA channel mappings. I was able to get things working again by only after spending half an hour resetting OTA and then running initial setup for OTA, and then rebooting the boxes. Watching TV and having a reliable DVR just should not be this hard. I hope this is not a sign of things to come in June.
