Thanks for the info, it is all I needed to know.
I'm not looking for feedback or trying to start a discussion but ill add a bit more info.
I'm not not even sure what a video with two series would be?
I use Artist and Series as a lists for video and documents.
For documents, its for the huge number of subseries/crossovers that happen between different comic series.
Also for when there are 2 authors working together.
For videos its mostly for adult oriented (similar to comic crossovers)
The workaround: No Series/Artist images for documents, and separate video views for media sub types
A lot of users create a list field like "Contributing Artists".
I have a plethora of soundtracks and compilation albums where artists work together as a one time deal.
Instead of 'Artist 1 and Artist 2' I use 'Artist 1; Artist 2'
Most of these artists also have full albums in my library.
Because i can't use lists with artist images this fills the artist list with hundreds of artists that only have one track.
This clutters up category and theater views with one time artists that don't have images.
The workaround: Exclude various artists and soundtracks from theater/category views.
I have been happily working with the way things are and will continue to do so.
Thanks again
