the hr20 works with any directv satellite, when u first fire it up, itll ask you to choose a satellite setting. the only con of using a 3lnb is that you are not going to get ur locals in hd when the launch in your area. if thats what ur anticipating, call dtv and get a kaku upgrade (5lnb), youre going to need it for future upgrades with hd. the good news with the 3lnb is that ull still receive the basic hd channels (70-79).
