I've searched everywhere and cannot find a way to remove that chair picture in Live TV. Any ideas?
Select a different background image.
Depend on your skin, it usually found here:
System > Settings > Appearance > Skin > Setting > Background
You can point to a folder where you keep the alternate background.
For your Home Menu backgrounds you have to ask in your particular skin forum.
The picture i want to remove is not the one you are talking about. That's for the background wallpaper for kodi. I'm talking about the one in TV channels with the small box to the right.
