I have a TIVO model HR10 250 that I would like to re-activate. Since it was last activated they installed a new SWM LNB dish. Can I use that dish together with the TIVO? I have access to the all the cable runs, the power inserter and the switch. If the TIVO will work with that dish, do I run the cable (I only need to use one tuner on the TIVO) from one of the ports on the switch? Thanks for any help.
