Thanks all. I managed it. For every movie I make catalog ($movie ($year)) in ZRating (with cast&crew thumbnail creation with role), and write in JRiver Actor field only name (without Role). There is no need to change code for this in JRiver.
Sorry for too many questions but I can't make work another one.
I want to use Links to Actors like one suggested by lepa - for example for director
field: LINK_Director - expression: If(IsEqual([Media Sub Type], Movie),Directed By ListItem([Director],0),)
and display via LINK_Director field
If I create for specified Actor:
field: LINK_Actor1 - expression: If(IsEqual([Media Sub Type], Movie),Movies with ListItem([Actor],0),)
it display movies with this actor but with only situation when this actor is listed first in another movies. For example Tom Hanks play in 20 movies in my collection, but when is listed as second actor (with Field LINK_Actor2), this expression shows only 4 (because in my movies he is listed second 4 times). Is there any solution for search in all fields? I hope someone will understand my poor english
