Hey,
Lately i bought a "Astrometa DVB-T/T2/C USB Tuner", some of you might know it.
I know it is a very cheap product but I saw linuxtv stating its compatibility with linux kernel 4.6 and higher, so I went for it.
I am running Ubuntu Server 16.04 with mainline kernel 4.13 and the device is properly detected and showing up as it should, even in tvh both frontends are shown.
I tried the device running w_scan and the results looked promising, I found pretty much every channel there is in my area using DVB-T2.
Then I enabled the correct DVB-Input in TVH and also added the frequencies for each mux manually (using w_scan output), forced the network to scan and waited for the results.
TVH finds zero services on the correct! muxes, although signal strength is shown and also decent while scanning.
Some additional info / suspicious outputs
