My installation is new. Have 4 Quattro LNBs connected to a Multiswitch and to a TBS6922 card and a TBS5922SE USB tuner. It all works except the it will only receive a signal from LNB1. i.e the DiSEqC switch is not working. I believe it's the drivers supplied. Has anyone got any older drivers for these cards. (or any other ideas). Help - desperate.
