UHD rips stutter and artifacts on screen

I tried backing up 3 UHD titles:

Dune, Scrooged, The Last Starfighter

All play on the computer with VLC, jellyfin in a web window. When I try to play them on my Hisense Android 4k TV (65H9G) or thru my Panasonic DP-UB820 I get severe stutter, and blocky artifacts on screen. I've also tried copying the mkv file to a USB 3.0 stick and have the same results.

Suggestions on resolving the playback issues to my TV or thru the UHD player?

We assume you are playing the full bandwidth original files with no recompression .. do you actually have the available bandwidth to do this?

You're talking about a REMUX right, often very large file sizes, increasingly so if you decide to keep multiple audio streams and subtitles, you've not encoded your rips? Have you tried a powered USB drive via your TV's media player or Panasonic UHD player instead of a bog standard USB drive/stick, saw someone mention a similar problem sometime back, audio/video sync issues until they used a powered USB drive.

Just an update. I finally had some time to work on this. Network bandwidth was the issue. The TV and Blu-ray player both only support 100Mbps on the wired connection. The counter intuitive solution was to go WiFi. The Blu-ray player and TV support WiFi 5 (802.11ac) and a 5Ghz 80Mhz channel did the trick.

Moral of the story, just because your wired infrastructure is 1Gbs or greater doesn't mean your client devices are.
