I have an older oval directv satellite dish that gets HD signals. It is not the new kind where everything streams from 1 box. In fact I have 4 owned hr24 receivers hooked up to it. I need twice as many lines so I can record on one channel and watch a different one, can I use a multiswitch for that? 2 lines are close to each other in the garage and 2 more are close in the attack. If I could add a multiswitch in both of those locations to double the number of lines I have I would in great shape. Is this possible? Thanks in advance for the help!
