All, I did a search in almost every D* forum and looked back a couple of months but, I didn't see anything related to my issue. I've had this HR20-100S for quite a while and have never had any trouble watching or recording anything from my OTA. Recently, shows that I record regularly have started to be very intermittent and sometimes I even get the message that D* could record the show. I have a wonderful Winegard antenna and am using a amplifier. I have tested that this antenna works fine with a TV outside of the D* connection. Has D* made any software mods recently that might have affected how the box processes the OTA signal? It's really aggravating, as the only way I can get my favorite show is OTA. Please let me know if there's any additional information you need. Thanks in advance... John P.S. Does the HR24 have OTA built in or do I need an adapter?
