Hi,
I've just done a complete fresh install of Emby server (also switched from Linux to Windows) and I'm having the same problem as before with Live TV images and a new one that has cropped up.
Firstly The images being displayed on the home screen and in the Live TV section are wrong.
Secondly for the channel logos, white space is being cut off form the images causing the aspect ratio to be different.
See screenshots for examples of both problems.
I'm running on Windows 10 Pro with DVBLink as my TV backend.
Hope someone can help!
