How to use gnutv with dvb-c

Question

I was using gnutv with DVB-T for some years, just with the commandline

gnutv -channels ~/channels.conf -out file somefilename STATION_NAME

channels.conf generated by w_scan -f c >channels_dvb-c.conf

Now i got a DVB-C receiver (combined with -T and -T2). I ran

w_scan -f c >channels_dvb-c.conf

And got a nice channel list with a lot of cable channels. But gnutv doesn't work:

# grep arte channels_dvb-c.conf
arte;ARD:418000:M256:C:6900:401=2:402=deu@3,403=mis,407=mul,408=fra:404:0:28724:41985:1051:0
arte HD;Unitymedia:114000:M256:C:6900:513=27:514=deu@3,515=fra:518;1521,1522:0:17113:9999:121:0
# gnutv -channels channels_dvb-c.conf -out null arte
Unable to find requested channel arte

What is the problem? I do not see if there are any options for using dvb-c are needed, but on the other hand there do not seem to be many docs about gnutv and DVB-C.

Answer 1

My command line for DVB-C looks like this:

gnutv -adapter 0 -frontend 0 -demux 0 -channels channels.conf -buffer 5000000000 -out file "output.ts" "arte HD"

This will record directly to the file output.ts.

I set the value for 'buffer' very high because I got errors while recording.

A line from my channels.conf (This is ONE line):

arte HD:114000000:INVERSION_AUTO:6900000:FEC_NONE:QAM_256:6661:6662+6663+6669:11120

The channels.conf file was created with the following command:

w_scan -fc -c DE -M > channels.conf

My Hardware is 'TT-TVStick® CT2-4400'.
