If the vidb and vidc (ts1 / ts2) bridge streams each single channel
correctly, but not both together then this is either a sram
configuration issue (the risc engine's workspace is being corrupted by
another risc channel), or your system has a pcie compatibility issue.
I've seen both of these issues in the past.
I don't have a hardware product with demodulators on vidb and c, so
that's not something I can repro.
Can you dual boot the same system under windows and remove any pcie
