[Lockos]

The playlist thing did nothing, I used the original playlist and modified it (I suppressed the banned addon rule as I no longer use it, I figured out those addons were killing kodi)

As for a translation :

Style -> Compact pannel
Background -> Color
Pannel label --> when highlited
Type of Widget -->Mediatheque
Art-->Poster
Case -->Case
Sort by-->predefined
Sort order -->predefined

What I really don't understand is that Poster and CD do show up in the infopannel, but not in the widgets, and only for some movies. It's really weird. Can it be an nfo thing ?

It could be. To rule out that any of the art is not properly cached, you could try this: Texture Cache Maintenance Utility I run it with the c option to ensure that all of my artwork is properly cached.

You do have to have python installed in order to run that utility.

It is not the nfo (tried a new one given by schimi)
This utility is like too hard to use, I'm kind of a noob at that, I,ve read the page but can't run it. I'm stuck, this is so frustrating...
