Awhile back I am sure you said when grabbing pvr artwork it looks in cach does that mean searches movies and episodes artwork cache? If so what is the criteria of the search.

All searchresults are stored in a persistant cache, the file called pvrdetails.xml. If that file is found for a certain title it will not look any further and use the details of that file. You can also save that file to your own recordings folder/share to provide the details yourself.
If you enabled downloading of artwork the artwork will also be stored in the folder of pvrdetails.xml, otherwise the pvrdetails.xml file will contain the web addresses to the artwork (and kodi texture cache handles the rest)
