I’m now experiencing my same setup transcoding dts tracks to ac3. Unless I force play override it does this.
Roku can be set to either pass through or auto and it exhibits the same behavior.
Preview and official channel. Anyone else?
I’m having exactly the same issue with a brand new 2021 Roku Express 4K+. Anything with DTS (Core or otherwise) lags the video as described by others. This replaces a very old Roku 3 that has absolutely no such issues.
Just upgraded to the new Streaming Stick 4k (3820R) and am experiencing the same issue. Any content with DTS audio causes the video to stutter when Direct Played. The only workaround I’ve found is to disable Direct Play, and allow Direct Streaming. This allows the content to be Direct Steamed, which seems to resolve the stutter issue.
However this is a less than ideal solution for the long term. @ljunkie any update from your side that you are able to provide at this time? Thanks!

Another new Streaming Stick 4K user here (3820X), experiencing exactly the same issue. Any DTS-encoded content experiences unwatchable severe video stuttering when trying to Direct Play. Disabling direct play fixes the stutter, however now my receiver only gets AC3 not DTS, so not a workable fix long term.
Adding another voice to those asking for an update on this. Seems crazy to me that such a known issue with easily re-creatable and consistent causes and symptoms is still present a year later, and across newer hardware.
I have a new Streaming Stick 4k(3820X) with the exact same issue. Video playback has 1-2 second stutter where it slows down and then picks back up. This issue only occurs when dealing with DTS audio tracks…I will note, when the audio track is DTS-HD, enabling the “allow DTS-HD” in plex audio config will allow the track to play without transcode and not stutter, but only for DTS-HD.
So is this a container (MKV) problem when DTS is involved? If I’m understanding correctly, when you disable direct play and only have direct stream, it will take apart the container and repackage the video/audio streams…in this case into the container “hls”, and play the package correctly.
The workarounds of manually forcing Dolby Digital in the roku app and disabling direct stream both work on this device. It looks like the fix for Roku Ultra 4800’s was built into update 6.7.6+. @ljunkie any updates on this same fix coming for the new streaming stick 4k?
Everyone could try this:
Can you browse to the Codecs folder in your Plex data directory.
“…/Library/Application Support/Plex Media Server/Codecs” in Linux.
Then once you find this folder DELETE EVERYTHING in it. (this is 100% safe)
Once you do this try playback and report back here.
I renamed both codec directories and restarted the service. Plex rebuilt the codec directories…I re-tested the issue and it still happens with the refreshed codec directories.
Hi, I have a Roku Streaming Stick 4k and also have this issue. At first I couldn’t figure out the cause so I started a thread: Jerky video on Streaming Stick 4K - #5 by jaydee77ca
However I just narrowed it down to direct play with DTS and MKV container and that lead me to this thread. I’m happy it’s not some weird unique issue with my setup but I’m sad that it’s been an issue for a long time. Hopefully it gets resolved soon.
I opened a ticket with Roku support on the issue and that went nowhere. At this point I’m unsure if this is a Roku problem or a Plex problem…right now the workaround of disabling DTS at the Roku audio layer seems to work so far.
