So I split DirecTV with my neighbors. I have one HD DVR and they have one SD DVR. They just bought a new LCD TV and they want to upgrade to HD DVR on it of course. However, they also want to keep the SD DVR hooked up to the old TV in another room.
Now, they live upstairs from me and it's a big PITA to run more cable up to their apartment. Can I get a Zinwell multiswitch and ONLY hook up the two cables that currently run up to their apartment into it to allow for two separate DVR boxes in their place OR do I HAVE to hook ALL FOUR cables that currently run from the dish into the multiswitch for it to work?
Basically, we will have two cables coming straight from the dish into my HD DVR downstairs, and two cables going upstairs, into a multiswitch and then splitting into two DVRs up there. Will this work?
I appreciate any help.
Edit: Also are these multiswitches powered? Are they safe for outdoor use?
