I acquired a relatively new slimline dish, the multiswitch, but no power inserter. I am considering upgrading to an HD DVR. But, I want to hook this dish up to my standard DVR in the meantime. This way I will be ready when I make the decision and I hear the larger dish gets better reception in the rain. I am currrently using a TIVO dvr that I own and a 15 year old sony dish. My big question is, can I hook my current SD hvr up with this slimline? Will I still need the power inserter? Will the power inserter damage my non-HD receiver? Thanks.
