The first receiver controls the data flow. So if you have receiver 1 on a V channel receiver 2 will only see V channels. Change receiver 1 to a H channel and receiver 2 will see H channels. I do not know if a dual output lnbf would allow you to view independantly or not. Receiver 2 would then be hooked directly to the lnbf.
