Videos immediately quit after playing

I am using the EpisodesScreen template for my Roku Channel development. I have multiple seasons with episodes. Am using AWS S3 going through a Cloudfront distribution. Everything seems to be fine, except when I attempt to play video content from the third season onward, I get the revolving “loading” circle but the video immediately quits and goes back to the episode detail screen. When I attempt to access those videos directly through my browser using the Cloudfront URL, it plays back fine. So I am able to access them outside of my Roky device/code. Very confused as to why this is happening as the first two seasons work great. Any suggestions?

Just discovered that it might have something to do with UHD video versus FHD. Is there a resolution/bandwidth limit in the Roku code?
