Hi,
Personally, I retrieve the logo pack dispo on the forum, and I rename the corresponding icon (for now only one chain to do).
Example:
AppData\Local\SmartDVB\Logos\RTS Un.png
Result:

It is a tedious job but in the end it will give a nice list.
For my part it is the cable of France (Numericable).
If I have time to do all the Numericable TV channels, I would put a .rar on the forum. Beware, however, of the French cable, the TV channels are not all the same, for example in Moselle, a lot of German TV channel, whereas in the Pyrénées-Atlantiques it would rather be Spanish channels.
Good courage bison1947 for the creation of your logos for your cable provider.
