Couple days ago the over the air channels went missing from the Guide on my HR20-700. Couldn't get them back until I did a red button reset. This is the first time for this to happen but other stange things have been happening from time to time. Hope it isn't going out becasue having the ATSC tuners is very handy here in SW Florida when the nearly daily evening thunderstorms roll by and the Satelites get lost. I just switch over to the -1 and its back on the local news. I wonder if anyone else has seen this happen.
