Hi all. Long time user of an RPI where I direct played pretty much anything I tried from my server, however it does not support HEVC/4K.

I have since switched to a Xaomi Mi Box which arrived today. After setup, I installed Plex however any file I play above 20Mbps just stutters/buffers/slows down/juddery and generally unplayable, this means I cannot Direct Play anything above 20,000 bitrate (quite a problem as i have a lot of high rips on my Plex server). I have a 320Mb/s Internet connection so I highly doubt that's the problem, although the Mi Box is only wifi. When changeing "Original file" to "Convert to 20Mb/s" i get no issues.

I run a rclone/node-gdrive-fuse setup using Google Drive, and I can download files upwards of 10Mb/s from Plex on my wired PC, so I'm not really sure what the problem may be.

Can anyone shed some light or give ideas as to a way to fix this?
