When I start up VLC and go Media->Capture Device->TV Digital and select DVB-T2 then Play, nothing happens, but selecting DVB-T then Play, VLC scans the entire spectrum and comes up with zip, zero, zilch then just restarts the scan. I have tried this with both an external and an internal aerial connected.
When I run w_scan -ft -cAU then the frequencies I would expect to see are:
184.5
191.5
212.5
219.5
226.5
529.5
536.5
543.5
550.5
557.5
but the output from w_scan with an external aerial is:
w_scan -ft -cAU
w_scan version 20141122 (compiled for DVB API 5.10)
using settings for AUSTRALIA
DVB aerial
DVB-T AU

Given that the low frequency tower is about 20km line of sight and the high frequency tower is 2km line of sight, and that I have no problem tuning either tower with a conventional TV, this problem is mystifying.
TIA,
