Actually, it seems most set top boxes contain some kind of amplifier (or
PCI cards have sensitivity issues), because I had the same issue.
I had to add a filter/amplifier to be able to run two cards in a
daisy-chain. Before that, the first card would work fine but the second
card would only tune some muxes and complain of bad signal. The STB
worked fine all along.
Try using an amplifier and see if that helps.
