Problem finding channels

[philipbonev]

Hi,

I installed NextPVR on my computer today - Pop!_OS 21.10. The site opens and finds my TV Tuner, but there seems to be a problem with finding channels.

The distro provided files in dtv-scan-tables package where wrong for my country bg-Sofia.
So I made myself one with current data using script I wrote:

Code:

#!/usr/bin/env bash
w_scan -ft -c BG -x > tv_dvbv3.conf
dvb-format-convert -I CHANNEL -O DVBV5 tv_dvbv3.conf tv_dvbv5.conf
dvbv5-scan tv_dvbv5.conf
cp tv_dvbv5.conf /usr/share/dvb/dvb-t/bg-Sofia

dvbv5-scan finds the tv channels ok:

Code:

dvbv5-scan /usr/share/dvb/dvb-t/bg-Sofia

       (0x00) Signal= -76,00dBm
Scanning frequency #4 490000000
       (0x00) Signal= -54,00dBm

The web interface does not show error, but in log files there is something like error:

So the question I have is - am i doing something wrong or is there a bug in the software?

Can you please post the logs showing an attempted scan?
