So to clarify, you want to be able to add a list of other movies in the collection that this one is part of (if it is a part of a collection) on the pre-playback screen where it shows the synopsis and actors, producers, etc and the video specs like resolution and audio specs?
Maybe a new row below the Actors that shows other members of that collection?
Or, if UI real estate is an issue, display a single clickable icon of the poster or graphic for the collection that the currently viewed title is a member of, which leads to the relevant collection page when selected.
Speaking of collection update in 7.4, I hope @james will consider add this feature.
It’s really annoying that very often when I go to the pre-play screen, I’m not sure if I own or watched other movies in that collection (movie series), so I have to go back and find the collection under the collection row in home screen.
