Hi I recently tried contacting Dish about upgrading my 2nd receiver to an 811 but they told me that since I already upgraded my 1st receiver (got a 510 back in January) earlier this year I do not qualify . Anyhow. They said that only once a year you can upgrade only one receiver. I am thinking about getting an 811 off ebay. I have a 119/100 + 148 system with one coax coming to my Receiver. If I get an 811 could I just use a splitter then connect the two feeds to each receiver (1--510 and 1-->811) and connect them to different inputs on my HDTV. Would this work ok? Any problems with this setup? Also in the future I may get the Voom channels and will get the 61.5 dish installed. Is there anything I would need to tell the installer to future proof for maybe a 942 in the future ? Thanks
