Problems with some digital copies of movies not showing up in purchased movies

tvOS & Apple TV Apps
I have many Blu-ray movies that come with a digital copy of the movie. Most give me no problem, but I've noticed a few that show up just fine in my iTunes library, but that won't show up in the purchased movies section on my Apple TV. Two examples of this are Source Code and Black Death. I know there are a couple of others, but those two are the ones that come to mind without me having to go through my library. What I want to know is whether or not there is a way to get them to show up, and if there is, how do I accomplish this? I know I could put the movies on another device and stream via Airplay, but number one, I don't know how to do that yet and two I really don't want to have to usee some complicated method just to access something that I should be able to access easily just as I do with my other movies. I would appreciate any information that might help me get my movies on the purchased list as they should be. Thanks, Chris
