Rpi3 new setup buffering

Hi,

Having issues with constant buffering and broken playback on RPI 3 running OSMC (latest stable release). I’m trying to locally stream from an old windows 7 PC (AMD A6 3670) through Samba. I’ve setup OSMC to connect to an emby server on the windows PC, but am using Samba to retrieve the video files.

Am having stuttering issues when playing back all videos I’ve tried. For consistency I’ll stick to the one video below (which is only 720p at this stage, and if we get improvement will try another 1080p video). Am trying now over wired ethernet, but have also tried over wireless (preference for wireless). Router is an Asus AC68U, located approximately 2 metres from the Pi, the WIndows 7 PC is wired to the Router at 1gb LAN.

Have tried disabling OMXPlayer and running MMAL, have tried disabling MMAL and running OMXPlayer, both with stereo stream decoding disabled.

Audio would be pass-through mode to a soundbar compatible with DTS and AC3.

Any help would be appreciated, I was hoping the rpi 3 would be a suitable downsize to this old AMD workhorse (which I’m using as a glorified NAS now).

Thanks

Always first thing to try to know if it is a network or codec issue is to copy the file locally on to the Pi and play it from there. If problem still there than it is a codec issue, if problem gone than network need to be checked.
First step there is trying to measure raw throughput between both devices with iperf.
