additionally you could easily setup tvheadend or (even vlc or mpv) and
look at it through kodi. i have a quattro also and i have
tvheadendusing it through a m3u channel list through the http command
to get a stream.
in my case on 192.168.1 network i just use:
http://192.168.1.146:5004/auto/v11.1
to get my channel 11.1 on the network address of my tuner.
