Tvheadend

Hi there,

I have the following setup with TvHeadend 4.3-295~ga9dffb7 or 4.2.3-19~g490b6f2:

SAT2IP Server: Digibox R1
Tuner 1: Single Cable to 2/1 Diseqc Switch (1.1 or 1.0). Diseqc position 1 goes to Quad LNB Astra 19,2 and Disqec position 2 goes to Twin LNB Hotbird 13,0
Tuner 2: Single cable to Quad LNB with Astra 19,2
Tuner 3: not used
Tuner 4: not used

Server: TvHeadend 4.3-295~ga9dffb7
Client: Kodi with TvHeadend Addon

I have configured under DVB-Inputs-> TV-Adapters-> Tuner 1 2 Satellite Positions and assigned Position 1 to Network Astra and the second to Hotbird.
But only Hotbird is working. TvHeadend is unable to switch to Astra on Tuner 1

Am I missing some special diseqc option?
I tried under DVB-Inputs->Networks to set the SAT>IP source number to 1 and 2, but it didnt work.

Could you please give an hint how to configure this right? Thanks
