How do we keep our course content from being stolen if we allow students to download videos and audio?

I wouldn’t worry about people stealing your content. These types of people are a tiny fraction of the good apples : ) The vast majority of students are in your program because they want to learn from you, not take advantage of you. These types of situations are rare and usually not worth stressing over.

That said, I’ve had my content stolen before. When it happens, my team sends a cease and desist letter, and that almost always shuts it down quickly. I don’t spend any more energy on it than that. I’d rather focus my energy on serving the amazing students who are showing up, doing the work, and respecting the program.
