My old setup was the Dish 500 dish with two outputs, one port on the left side and one port on the right side of the LNB which can be separated from the end of the "arm" of the dish. My receiver then was the 4922 which continues to work. I'm now using the DVR 625. We're using one TV. Right now all I have is one tuner working on the DVR, not both. I understand from other forums I've read that the simplest solution with what is now called a legacy dish is to run a 2nd wire from the 2nd port on the LNB and run it to 2nd LNB port on the DVR. My first question is will this setup work? My next is should I invest in the LNB with the twin ports on one side and one port on the other and what is that particular piece called. Thank you; any advice and help will be deeply appreciated.
