Thanks for your reply, but both those tricks didn't work. In fact, it appears the file I want to remove is haunted LOL
Let me explain everything that I've tried.
1. Settings > videos > Show all videos - SWITCHED OFF. This is the most effective method, but doesn't solve the problem. It deletes all purchased movies, TV shows, and music videos EXCEPT the one music video that I want off there. There is no edit button on the top right corner of the videos area inside the default Videos app. The haunted music video that still displays, is kept in the cloud, because the cloud logo appears in the lower right hand corner of that video's thumbnail. The weird thing, is that every other music video that I've purchased, is gone once I've switched off this setting EXCEPT for this one. Very, very weird.
2. Settings > iCloud > iCloud Drive - SWITCHED OFF.
3. Settings > iCloud > Backup - SWITCHED OFF.
4. Settings > iTunes & App Store > Show all - music SWITCHED OFF and videos SWITCHED OFF.
5. Settings > Music > Show All Music - SWITCHED OFF.
6. Settings > General > Useage > Manage Storage - MUSIC VIDEO I WANT TO DELETE FROM THIS SECTION IS NOT SHOWING UP AS AVAILABLE TO DELETE.
