• Quality: as high as possible
• When adding a new logo, also ad the "# channelname" in the DVB-S/S2 section when it's a new DVB-C or DVB-T channel.
• It's also possible to provide a "white" version of a logo, wich should be placed in the folder "/picons/white".

With the help of @tkurbad's python script piconlinks.py, you can speed up the process of linking the channels. You basically feed it your "channels.conf" file and the location of the git repo you cloned containing the channel logos, it then will try to match as many channels as possible.

@pipelka also supplies a tool called serviceref with the xvdr-plugin, wich you feed it also your "channels.conf" and it then spits out a file with all your channel names followed with their serviceref.
