so you're saying this is not actually a DV playback problem but a general buffering problem? i will look into that.
i was under the impression that "normal" HDR UHD mkvs (even high-bitrate) played just fine. but i'll have a closer look
I suspect so, especially if you're also using SMB. I came across the first title that cannot be reliably played over SMB as an mkv:. Tremors. The bitrate is consistently too high, that eventually the cache exhausts itself because the Shield is unable to keep it filled, and once exhausted playback stutters like crazy.
so what is a good buffer amount to set in advanced settings for a device like shield pro?
Thank you.
For a movie like Tremors. Basically no amount will allow you to play it without exhausting it and then buffering. At least over the SMB built into Kodi. I suspect Gemini Man would also induce this, but that's a particularly rare and corner case, since it's both DV FEL (IME, FEL DV tends to be substantially more overhead than the other P7 DV types) and 59.94fps. That latter bit is what really sets that title apart, especially with the higher bitrate.
Example 4 is probably fine, here:
https://kodi.wiki/view/HOW-TO:Modify_the_video_cache I tried setting it to double that amount, but tbh it didn't really result in an appreciable benefit. You need to heed the warning, and DO NOT set the cache value to 0. If you do you will likely wear out the 16GB flash chip in your Shield in short order and kill the device.

fandangos : Btw I came across my first DV glitch. Not sure what happened, but after playing an DV-enabled mkv in Kodi, it resulted in a black screen. That perpetuated to basically DV playback with any other app I had, such as Prime, Movies Anywhere and Vudu. I actually had to restart my Shield to fix it. It's almost like the engine/codec (or whatever it is) that handles DV playback crashed. I haven't been able to reproduce it though, just that one time. Still thought it would be worthwhile.
One other thing, I have noticed a few times that Kodi gets rather stubborn and repeated failsly to play a particular mkv title (like even after 3 attempts). The best resolution I've found so far is actually exit the app completely (with the "power icon" next to settings) and relaunch the app. I'm pretty sure if you see the splash screen when you select Kodi from the home screens, that means it's launching completely, instead of just resuming from app sleep.
