Tom-- just saw your reply. Dish and Univision, a Spanish channel, continue to fight. I called to ask about it, and they offered the OTA so that I can pick up my local Univision channel. Try that.
I resurface this initial issue because my OTA antenna continues to act wacky. I can attest that, AT TIMES, it tunes to a channel immediately (with a bit of a delay, but I imagine that it's normal since it's going via USB. A satellite channel tunes instantaneously). So, I can say that my antenna works fine. But, many times, like right now for example, I will direct tune to a local channel and it continues to try to get a signal; it hasn't found any of my local channels in the last 20 minutes. Mind you, when I go into OTA in the settings, all the channels in the guide show a strong (100) signal. I just went into each channel and let it determine the signal strength (in the IN GUIDE column). I can now tune instantly to each channel. Wow.
So. Is it that the tuner "forgets" the signal strength of each channel, or something like that?
