The port 4 bit has to do with using Legacy receivers that can only see 3 birds, and can not see the FSS one, so FSS goes on port 4. It's old and rare - don't worry about it.Tekken said:Heh, I thought 129,110,119,61.5 are all DBS Satellites and Port 4 on the DPP 44 was for FSS LNB's only. What ever happened to the 61.5 programming being avail on the 129 Satellite anyways?
