PVR H264 Stream Buffering

Hi,

Using Kodi 17, I’m having issues with H264 streams buffering, but only when starting playback. It seems to take about 60 – 90 seconds from opening the stream to completely fill the cache to 100% and then they play fine. This is happening on all streams from multiple different sources.

Is there any advanced setting placements I need to make to help prevent this from happening? Using a RPI3. OSMC if this makes a difference.

Thanks
