I am considering switching to Dish, and I am having a really hard time trying to understand the connections with second TVs. I will have 4 rooms to include: Family Room: HD Master BR: SD Den: SD Second BR: SD From what I understand I could do this with 2 DVRs-1 HD & 1 SD. How exactly do you make the connections to the second TVs? Is there a document somewhere that shows the options in wiring setup? I haven't been able to find one.
