Visited aunt and uncle in NC. they have some really vintage dtv equipment. 3 Hughes sd-hbh receivers and a single LNB dish. The receivers were made in 9/04 and was wondering how much longer can they get by with this old equipment Please give me your thoughts on this. I really am trying to get them to get with the times now with HD receivers and the 3 LNB dish. How hard is it to upgrade the equipment?
