I've got Dish Network but they aren't offering local HDs in my area. So I'm looking to switch. Any reviews? In the past when I've looked at DirectTV the upfront fees for 2 HD DVRs and 2 SD TVs wasn't worth it. Now the whol home DVR thing has me interested. Any reviews? If the show is recorded in HD is it replayed in HD (assuming an HD tuner is connected)? If you hook up more than one DVR can you record 4 shows at once?
