Hi,

Still in my new setup, copying the muxes configuration from my old setup (which is still runing perfectly).

When I set a muxes with this setup (I'm from belgium):

Freq : 314000000
Sym : 6875000
Const : QAM/256

I have no services to map.

I tried to enable logs and seen this:

The QAM64 are working normaly.

Have an idea?

Thank you

Sundtek:
Which System do you use?
Which Tuner do you use? I think that's a MediaTV Pro or Digital Home from before 2014?

What do following commands show up when tvheadend is not started (and when nothing is connected in /opt/bin/mediaclient --lc)
/opt/bin/mediaclient -m DVBC -f 314000000 -S 6875000 -M Q256
/opt/bin/mediaclient --tsscan /dev/dvb/adapter0/dvr0

I'm running under Unraid

Tvheadend as a docker container

It's correct, it's a MediaTV Pro older than 2014

Sundtek:
What does lsusb -v show up? I guess the device is set to the wrong device mode (a device mode which is not supported by that system) however the old devices are configurable.

QAM256 is not the problem here for sure.
