[linux-dvb] Re: Galaxis-DVBsat card with pass-through

[Frantisek Bocek <bocekf@iol.cz>]

Hi,

I don't know exactly about the card, but LNB loop-through output  on 'normal' receivers usually works this way:

1. The signal is routed to the loop-out all the time.
2. But, the control signals (22khz,12/18V) are accepted from the OUT only when the master receiver is switched off.

I think  that this exactly explain  what you are experiencing. (the signal is on TV out but the control signals are determined by the DVB software, whose may be same/different depending on the situation and therefore some channels are not visible)

The question is what "switched off" means for the DVB card, because AFAIK the PC must powered ON all the time
to pass the signal to LNB OUT! I think there must be a such function in the software/driver which enables the LNB OUT.


Regards,
Frantisek
