I might add i use an over the air antenna and no cable, so that may make a difference but when the guide won't load it doesn't show any of my channels. When you go to video inputs, built in tuner settings, channels, first change the Rocco guide off then back on, then i just redid the auto program, once that was complete the channels reappeared in the Rocco guide saying no info i did it on a monday night and i was up late till about 1:30 watching TV. In the morning info was in the guide, sorry if i sounded condescending and i guess my instructions were a bit vague. Also this probably only worlds like this with ota antenna and different with a cable box. Hope this is a little clearer and helps so people don't have to do a unnessisarry hard reset which is super annoying.
