SOLVED: Tracking/Starting Slow

[JellyEll]

This has definitely sped a lot up, thank you.

I'm struggling with a film, Oppenheimer, @ 4k (18GB/3hours). It stutters for ~20 seconds every ~20 seconds or so.
Would be icing on the cake to get this working, as I don't think the service has ever ran 4k films without stutter.

Can you see what the issue is, based on logs? I'm assuming the hardware is capable. The internet speed seems fast enough.

If I need to raise another thread, or if you can point me to things I should be looking at, thank you. I get you've helped me with my original problem!
