Hi all!
I am very glad that find this forum! I want using my tp-link 1043v1 to 100% and install openwrt 15.05 and tvheadend from this site. DVB-S2 device is install correctly and i can use this from tvheadend.
After adding mux, tvheadend find all other. But then i choose "mapping services" whith all options enabled (Check availability, Include encrypted services etc.) all encrypted channels failed. CAs section works fine
Ok, when i try play service without mapping via VLC, thveadend say
