Is network scaning enabled?

The network discovery is set to new muxes + changed muxes.

What OS
what driver?

Hi, I have the same turner and ran into this problem. When I scanned the default muxes for USA local channels, I only received a few. I corrected this problem by turning off 3 of the tuners and rescanning the predefined muxes with 1 tuner only. I had to rescan a few times before all channels muxes were loaded. Once you receive the desired muxes and map the channels, turn all of the other remaining 3 turners back on within "TV ADAPTERS." DO NOT rescan after you turn these tuners back on. They should automatically tune in and recognize the muxes when played by your clients.

Good luck

@ Lisa White your device Hauppauge model 165100 is
total different from rest of the world Hauppauge model 166100.
We use DVB standard not ATSC

If there is a good signal and operator use correct NIT scan process pass for seconds.
Else need to be created init scan file with w-scan with TVHeaend to use as pre-defined.

Hi Gabor,

did you manage to solve your issue?

I followed https://tvheadend.org/boards/5/topics/46257 and tried

./w_scan2 -f c -c HU

w_scan2-1.0.14 (compiled for DVB API 5.11)
https://github.com/stefantalpalaru/w_scan2

using settings for HUNGARY
Country identifier HU not defined. Using defaults.
scan type CABLE, channellist 4
output format vdr-2.0
output charset 'UTF-8', use -C <charset> to override
Info: using DVB adapter auto detection.
    /dev/dvb/adapter0/frontend0 -> CABLE "Silicon Labs Si2168": very good :-))

Using CABLE frontend (adapter /dev/dvb/adapter0/frontend0)
-_-_-_-_ Getting frontend capabilities-_-_-_-_
Using DVB API 5.11
frontend 'Silicon Labs Si2168' supports
INVERSION_AUTO
QAM_AUTO
FEC_AUTO
FREQ (48.00MHz ... 870.00MHz)
SRATE (1.000MSym/s ... 7.200MSym/s)
