Personally I would try to upgrade to a wireless Genie and two slaves for starters.
Then if it were me I would hardwire from a convenient place outside to the Genie, actually to the power inserter, where I could feed the video bridge. Once wired then all you need to do is connect the slaves to power and the TV. With the Genie you can record up to 5 programs at once.
Correctly hardwiring is not difficult, just takes some preplanning some RG6 coax, a few fittings the crimping tools and once done means only one hookup coax from the dish.
