Transcode 4K

Is there anything that can done on this or at this stage should I be looking at alternate solutions ?

What I have and have done to test;

PC1

Win 10 1803 17134.191
Intel Core i7 8700
Memory 32GB
NVidia GeForce GTX1070

Windows Updates

July 16, 2018—KB4345421 (OS Build 17134.167)
July 10, 2018—KB4338819 (OS Build 17134.165)

PMS 1.13.5.5291

5 Moves all 4K
All failed with Hardware Transcoding Enabled and Disabled.

PC2 - Clean Build 2 weeks ago.

Win 10 Pro 1803 17134.191
Intel Core i7-3770 CPU
NVIDIA GeForce GTX 660

Windows Updates

July 24, 2018—KB4340917 (OS Build 17134.191)
July 16, 2018—KB4345421 (OS Build 17134.167)
July 10, 2018—KB4338819 (OS Build 17134.165)

Both are connected to USB3 External Storage.

At this stage I’m almost ready to start using Handbrake and iTunes.Plex Media (2.3 MB)

I’d appreciate any ideas at this stage
