Can't trust my one year old replacement HR-21-200 to view or record channels all over the "dial" at various times. Today tried to watch hour old NCIS recording and got instant keep or delete request. Tuned through about 10 channels before I got a watchable one and then worked backwards without further issue. I guess it will be best to call CSRs when I have a no signal avail. channel showing. I thought it was associated with LIL, but doesn't seem to be after looking at this instance.
