So what is my option then? I have to move these movies to the 'photo' app and then get an app to lock them? That means I have to sync the folder which is just stupid. I hate syncing. I would rather drag and drop.
Go check out some of the apps listed. Read their description in the app store. Stop asking us to do your basic research. Your question has been answered repeatedly. You've been given a solution that works for many other people. You've even been directed to several apps, by name.
Are you looking for someone to just do the work for you? You don't need to sync. You don't need to drag and drop. You NEED to open the app store and start answering some questions for yourself. That or listen to the people who are trying to help.
It's obvious from your replies that you have no clue how these apps work. So go find out.
