My current DirecTV setup (all owned). House: 1. A samsung 303 like it but have had problems refreshing menus. 2. 2 RCA's, don't remember models but all are from the early 2000's & NO Problems. 3. 1 RCA from 1998 and no problem. Motorhome: 1. The dome antenna is a King-Dome 9702 (late serial number) and NOT HD Directv capable. Don't want to upgrade at this time. 2. 2 Samsung recievers, one a Sir-303W & a Sir-70. First I want to OWN the receivers not lease from Direct. I want HD for the house and receiving SD via the King-Dome via a HD Receivers in the motorhome is OK. What receivers does everyone recommend for this "upgrading step" to HD? And any problems I should anticipate either with Direct or installing? Also, I would like to standardize on one make/model for less confusion & backups.
