I have the film now and it looks amazing! The only problem I’m having is that the playback is very choppy/laggy at the start. After about 5 minutes it plays fine. And it always gets stuck on exactly the same parts every time. After it gets stuck it starts but is very choppy and there is no sound. But if I pause and go back it plays fine!
I and viewing the 4k on my TV through an external harddrive.

If anyone could give me any advice I’d really appreciate it. Most of the film plays fine and it is honestly the best I’ve ever seen star wars.
