Thinking about this a quattro would make sense. If by sheer chance one of the pair cables on tuner 1 in is on the low band horizontal lnb connection. And the other is on the say the high band vertical or another. Checking the orihinal pdf list for, what hat bands can be received should sort it out.

Bought a real QUAD LNB and all the channels came back immediately. As luck would have it, a week after getting it back up and working my HB-1000S died. I sent it off for repair but was told that it's dead. Been looking for a replacement only to discover that Humax no longer make FreeSat boxes and the FreeSat branded ones have become monstrously expensive! What's that all about? Even the basic model costs triple the price of my HB-1000S and it doesn't even accept an external hard drive! Oh well....
