Tvheadend

Hi. The system scans 7 muxes but never finds a single service. Thanks for the help.

Tuner works correctly since "vlc channels.conf" works (after w_scan -ft -X -c ES > channels.conf)

The environment:
Linux raspberrypi 4.19.97-v7l+ (raspbian buster) with DVB TV HAT (Sony CXD2880 TV tuner)
HTS Tvheadend 4.2.8-34~g24a2f59e9. Also tried with tvheadend_4.3-1857~g221c29b40~raspbianbuster_armhf with the same result.

w_scan works fine and the muxes are configured as indicated by the w_scan output.
