Tvheadend

Hi,

I am trying to setup a Tvheadend (4.2) server on my Rock64 running LibreELEC (9.0.1) and using a Sony Play TV DVB-T adapter. I am located in Australia and am attempting to scan channels using au-Melbourne muxes, but for most of the muxes I get a failed result and only end up with 1/4 - 1/3 of the expected channels.

I have been able to successfully tune all desired channels using the same antenna and Mux to both a Raspberry Pi 2B and Vero 4k+ (both running OSMC) so that leads me to think that it's not a signal issue. I suspect that it's an issue with the adapter or maybe adapter firmware, but really I'm not sure.

Is someone able to help me work out why it's not working? What further information/debug information can I provide to make this process easier?

P.S. I have run w_scan on the Rock64 and that finds all expected channels.

Thanks in advance
