Cache problem / video stuttering

  • Hi,

    I need your help configuring my libreelec.
    Libreelec is running on my new Pi 3.

    I've installed the actual stable version from libreelec and afterwards the actuall build from milhouse (kodi.tv forum).
    I know that this is not a stable release, but I'd like to watch Amazon Prime, which is nearly working out of the box with his release.

    The problem I have is, that the video playback is stuttering after 20-30 seconds.
    The Pi is just connected via WiFi to my router and is only getting a round about 50-60Mbit/s. WiFi connection.
    My first thought was, that this connection is to slow. To disprove this, I put my PS4 into the same room, same position. The PS4 connections is as slow as the Pi's.
    If I watch Amazon Prime there, I got no problem.
    Another thing I did to disprove it, is that I've connected my Pi via PowerLAN adapter. Same here.

    So I was adjusting the cache settings in advancedsettings.xml, in hope that this will help.
    Actually it didn't help. Video playback from Amazon is still stuttering.

    Does anyone can help my solving this problem?

    Here are my cache settings:
