First of all, thank you for continuing the project under a different name. I greatly appreciate your efforts. I had the opportunity to test the application. Unfortunately, the logos cannot be displayed reasonably. I don't know if it's because of formatting the files. Transparent PNG was created via the Photoshop application. Casper CG Client on layer 1x displays the logos or the .svg files.
The .svg files are displayed with PlyCast in the following format "file:///D:/MediaPool/000-Logo/CTV-Logo.svg" as source indication in the logo .xml.

In the cg.xml the files with the "C:mediapoollogos" are not read.
