Advertisements We have a new HD OTA channel in our area. It comes in with a strong signal and good picture. However, I have noticed a strange problem when watching this new channel. My DirecTV HD Tivo (version 6.3d) keeps freezing up. If I leave it on the channel for more than a minute or two and then click a button on the remote, such as guide, info or channel up or down, the display freezes up and the remote and even the buttons on the receiver itself will not do anything. The program keeps playing, but the guide or info display never goes away and I can't change channels or go into the menus, "now playing" list or anything else and finally have to unplug it and reboot. This has happened at least 10 times since I first started receiving the channel. At first I thought it must be a problem with my receiver, but it never happened before and does not happen on any other channels. Today I left in on another channel for several hours with no problem and then changed over to the new channel and within 3 minutes the receiver froze. Could something in an OTA signal cause a receiver to freeze up like that?
