I have not had to fly commercial in many years.

I have a business trip scheduled soon.
I have a collection of DVDs that I want to reformat to play on my iPhone 16 Pro.
Back when I had my iPhone 5S, I had to fly to Dulles. I was supposed to arrive at 2:30 PM but I did not get to my hotel room until 1:00 AM. I sat and watched some of my favorite movies, Outlaw Josey Wales, Blazing Saddles, and others.
Now to get a commercial DVD copied to my iPhone, and have it work is a struggle. I have no intention of sharing the movies, I just want to watch a DVD that I paid for.
Any ideas on how to make that happen?
And yes, I have DVD - Blue Ray reader & burner on my computer. I have Handbrake and VLC Media player loaded on my system.
