From my experience, there are differences between receivers. I have an Openbox s9 and a pansat 9200 connected to the same dish, using a dual .2 lnb and separate feeds from the dish to the receivers. The open box is very happy with Montana, LPB and OETA and well as the other PBS channels ( I do have a occasional glitch on Montana, but not enough to be a deal killer). The pansat will not receive Montana, and OETA and LPB are iffy, other channels are good. If I switch the cables, the differences remain with the receiver. The dish is a re-purposed HughesNet (approx 1m).
