Livestream stuttering

I’m using LibreElec 7.0.3 on my RPi 3 and I’m – as the thread title suggests – eperiencing livestream stutters. I’m able to watch YouTube, or stream videos from my NAS, but many Internet livestreams start stuttering up to a point, where the stream becomes unwatchable.

This is my advancedsettings.xml file:

Code:
<advancedsettings>
<network>
<cachemembuffersize>104857600</cachemembuffersize>
<readbufferfactor>50</readbufferfactor>
</network>
<pvr>
<minvideocachelevel>60</minvideocachelevel>
<minaudiocachelevel>60</minaudiocachelevel>
</pvr>
</advancedsettings>

Even though I’ve increased my membuffersize up to 100MiB, it still does not prevent stuttering on my pvr for instance. (Although, I haven’t figured out what minvideo- and minaudocachelevel exactly accomplish). Is there anything else I might be missing? I have tested they streams in my browser and they seem to work fine, therefore I assume this is an issue on my end.

Thanks for thelp!
