We are looking at going to Hopper. We have 722 now and 4 tvs. Will I need 1 hopper and 1 mirrored joey? 2 tvs are HD, the other 2 SD. I don't mind 2 of the tvs being mirrored. I get confused reading the different ways to configure.
Mirroring with the Hopper/Joey system is not as simple as with a 722. At each HD tv location you will need to install an rf modulator. The feed from this modulator must travel back to your distribution on a separate cable from your hopper/joey signal cable. At your distribution this 2nd cable will just be barreled thru to each of the other 2 rooms and use channel 3 or 4 to view the feed from the hopper or joey.
