Thanks, I don't have a unit in front of me at the moment but I'm pretty sure the problem is that in the software there is no option to choose loopthrough. I've tried both openvix and openatv.
You're misunderstanding me. I'm not wanting to connect an output or split the cable and send it to another box.
The vu+duo boxes for example have internal loopthrough, connecting the dual sat tuners together so that you can record something and watch another channel at the same time, as long as the channels are on the same polarisation (even with one cable).
With the SF8008 this doesn't appear to be the case. There is no option in the software to loop the two tuners together.
Yes it's a dual sat tuner https://www.satking.de/sat--co/tv-r...hevc-e2-linux-dual-wifi-twin-dvb-s2x-receiver
Yes, have tried other images and the option just isn't there. It's a shame because it's almost the perfect box.
