I am thinking about buying a HR20 and have a question about hooking it up. The room I want to install it in only has 1 line going in, can I use a multiswich from that line to create 2 lines for the 2 inputs on the HR20?
You can use it with 1 line, you just won't be able to switch the channel once you/it starts recording. The dish (LNB) can feed upto 4 lines without a multiswitch.
