Your problem is somewhere between demod and bus interface. Tuner and
demod are working as demod is able to gain lock. Interface between demod
and bus interface - bridge - (USB, PCI) is transport stream (aka mpeg
TS). There is two main wiring used, serial ts and parallel ts. Check
that first. Both demod and bridge should be configured properly.

If TS interface it is correct then bug is somewhere in bridge settings.
