help with nfo files.

Hello,
I have problems with nfo files. I use Krypton with titan skin
Worries 1:
I try to put a fanart image in the actors tags. Thumb (poster.jpg) works but not fanart (fanart1.jpg). Is there another tag?
Worries 2:
I use library video node with a smartplaylist. I created a node actors-serie that shows me only the actors and works well but genres-serie does not work. I also tried with common movie but nothing either. I have absolutely no genre that appears

Thank you for your help.
