Basically i want to dump as much of the video to RAM as possible.

Is this because MADvr doesn't respect the cache or has its own cache settings? If so where could I find those?

I'm using 16.1 for the support of DVBViewer.

Perhaps there's some setting in the madvr configuration that could be causing this?

Maybe it's an add-on in the background? Are you using Sanear (the internal DSPlayer audio renderer) for audio rendering? Did you choose D3D11 Native hardware decoding for video decoding purposes in LAV Video? Are there any active subtitles during playback?

Thanks, great checklist! I made quite a bit of diagnosing based on them!  I also captured some video to demonstrate the stutter. These are linked below.

Here's some answers based on your suggestions and what I did based on them.

I have a wireless mouse + keyboard combo connected by USB to the PC but I'm not using/moving the mouse during playback in Kodi / Mediaportal. I also have a Xbox One wireless controller adapter connected by USB but the controller is turned off when using Kodi/Mediaportal. I use MCE IR-remote to control Kodi/Mediaportal/MPC-BE. (A Logitech Harmony remote and an official MS MCE USB IR-receiver). -> I tried unplugging all USB devices except MCE remote. I saw now difference in the stutter problem. Then I plugged all the USB devices back and then unplugged MCE remote IR. This made no difference either.

Yes, I read earlier from the MadVR/Dsplayer guides that OSD's causes stutter. However this stutter happens when OSD is not visible. I'm using Sanear audio renderer as per the DSplayer guide. I have subtitles enabled in Kodi and MPC-BE. I use Xysubfilter in Kodi and MPC-BE configured according to the guide here.

As for Kodi addons, I'm using Titan skin, Trakt, extended info, MCEremote etc. Basically only addons from Kodi official repo. I made a clean install with Kodi DSplayer deleting all settings from previous normal Kodi installations. I've only added addons related to Titan skin (Trakt, fanart handling etc.) and MCEremote addon with which you can map keyboard keys to MCE remote buttons.

I was using DXVA2 Copyback in Lav filters for hardware decoding but changed it now to D3D11. I don't see any difference with this change in the stutter problem.

I was using NGU Sharp in MadVR for image upscaling and changed it now to Jinc. My initial impression is that it might have very slightly reduced some stutter.


I found a perfect scene to demonstrate this stuttering problem in the movie Aliens. I ran through it several dozen times both in Kodi and MPC-BE first swapping between DXVA2 Copyback and D3D11 and in MadVR upscaling NGU Sharp / Jinc and the unpluggin USB devices etc. I found out that MPC-BE also occasionally has this stutter problem but it is less frequent and not nearly as bad as in Kodi.

The stutter problem doesn't happen always. It varies both in MPC-BE and Kodi. In Kodi it is worse. But occasionally MPC-BE playback stutters quite a bit as well.


Here are links to the videos I captured to demonstrate this stuttering (approx 30MB per video):

(sorry for the reflections from the screen)

My Aliens rip is a HEVC encode with DD5.1 audio bitstreamed to my Denon AVR.


I don't know if this matters considering this problem but I run a dual HDMI setup in Win10 with the second screen as an extended desktop. From Radeon GPU a HDMI cable to TV and a second HDMI with a Displayport adapter to AVR to bitstream HD-audio. I was unable to get HDR passthrough working by having a single HDMI to AVR and from there to TV.

Sorry about this long post. I'm glad if you had the enegy to read through it. Hopefully a fix can be found!
