Going to move into new house in a couple weeks, thinking about updating system. My Parents live with me in a different part of house. Right now I have two dvr's and one 301 box on my account. My parents have to have their own dvr so the kids don't mess stuff up. Can I update one of my dvr's to hopper3 and still have my parents regular dvr? Will I have to update both to make this work? I now about the solo switch but not sure if normal dvr will work off it. I want to drop the 301 and get a joey to replace it, does the hopper3 still run two tv's ? I know a lot of questions but forums have a lot of smart people to ask. Can I have two hopper3's in one house if I update both? Not sure but I think I own one of the dvr's, so can I just get one off ebay. Not sure dish would upgrade both for free,been a customer for about 12 years now.
