Astrometa DVB-T/T2/C+FM+DAB - TV Tuner MN88473 ( DVB-C can't scan) x86_64

psycmos · November 14, 2017 at 12:35 PM

I'm using the LibreELEC-Generic.x86_64-8.2.0, and i can get the Tuner MN88473 listed in tvheadend correct ( DVB-C and T /T2).
I can scan channels in DVB-T/T2 but in DVB-C scan channels option ,not appear in list.

Somebody have any solution for this?
Best Regards, Nuno

could you install the dvb-tools addon, reboot

stop/deactivate tvheadend, connect via ssh and start an search with w_scan then it should show somehting

then it might be some Tvh setting at scan, could you make some pics of the Tvh -> configuration -> dvb inputs -> networks -> your network
