That's the screen from MovingPictures. Script here doesn't have any relation with that plugin. You should try to ask here for help in that : Moving Pictures - MediaPortal Forum
This is an XML and no CSS Script Datei (C:\ProgramData\Team MediaPortal\MediaPortal\scripts\MovieInfo).
I have try in Mediaportal Konfiguration / Video Database /Update Grabber script Update the scraper.
But after the UP Date, teh same results. No Cover or Discrption.
