I don't have DirecTV but my father-in-law does. As an early Christmas gift we are giving him the HR20-700 plus a year of HD service. I bought one last week at Best Buy and sent it to him where he received it yesterday and has an install set up for the 21st. I have asked them to set up an OTA antenna as they only receive 2 channels for locals in Vero Beach. But, of course, the OTA doesn't work yet on the HR20, I'm hoping the installer can deal with that as I'm pretty sure my father-in-law doesn't have an ATSC tuner in the house. My end goal is to get waivers for the channels they don't get but I'm not sure how many that is. So my question for all you smart and helpful people. Is there anything else I should do to tell the installer and/or DirecTV before the installer is actually there? My father-in-law, while a pretty smart fellow about most things, won't know to ask the right questions so I want to do as much as possible remotely. Thanks for any and all help. -Bret P.S. Thanks for the BestBuy get some money back tip. I'm off for my $100 at lunch.
