I have installed an OTA antenna and have acquired a CBS and PBS station that show up in yellow when looking at the guide. At first "Digital Service" was the only entry in the program info. area for both stations. A day has passed, and the CBS station has all the programming info. filled in now, but not the PBS station, which still shows "Digital Service" across the entire info. field. While I can view whatever is on PBS by selecting it from the guide, I can't record any programs because there is no program info. to generate a timer. Anybody know what's happening here?
