I'm currently downloading a show that is on a service to which I subscribe
I have a Galaxy Tab S7 and for a trip to Spain I downloaded some stuff to watch on the flight. When I got on the plane none of the stuff downloaded on Disney+ would play. Maybe an issue with downloading to the SD card? I don't know, but regardless Disney offers SD card as a download destination so they should make sure it is working.
So now I'm here pirating a show that should be available to me through a service I pay for. Gabe was right, piracy is a service problem.
I've done some research and I think the problem isn't that it's adding bars, but that it doesn't fill the 4:3 material to the full height of a 16:10 screen, it just stops at 16:9.
I don't mind that for 16:9 content or other content that is wider but it's annoying that the 4:3 material doesn't use the full height of my screen.
