Hi! I currently have one dvr (r15) hooked up in the living room. In 2 bedrooms I have regular receivers that I'd like to change to dvr's. A couple questions..is it cheaper to buy the receiver (s) from eBay (can get them for under 100), etc or should I call dtv? They don't have a great special going on for current customers, I certainly don't want a 2 year commitment! If I do buy outright from someone else do I just call dtv and tell them I have hooked up new dvr's and give them a serial number or something? Can I install the receiver myself (is it just plug in/hook up and go?). Do I need anything else special? Meaning, can I hook up 1-2 more dvr's without needing a different dish or anything, just the wire coming in to the plain receiver now? Also, will I be able to watch/tape two channels on each receiver such as someone is sitting in living room watching 2 channels while someone else is in a bedroom watching 2 channels? Thanks for any help, I'm almost clueless on all this stuff!!!!!
