Did you manage to set up the card?
Reading the description for the card:
https://www.tbsdtv.com/products/tbs6909-dvb-s2-8-tuner-pcie-card.html
Connections: PCI Express - 4x RF IN
TBS6909 has 8 Tuners & Demodulators, but it only has 4 inputs, because it has a
multiswitch inside,
defining 4 inputs to receive 4 single polarity signals( Input0=VL; Input 1=VH; Input 2=HL; Input3=HH)
So if I understand this properly, allowing you to receive input from multiswitch that has 4 satellites connected?
(Sat A - VL, VH, HL, HH),
(Sat B - VL, VH, HL, HH),
(Sat C - VL, VH, HL, HH),
(Sat D - VL, VH, HL, HH).
How do you get that amount of coax cables from the roof inside your house?
