Tvheadend

I'm using TVHE HTSP Client for Kodi on a remote site.

I can watch live TV perfectly via HTSP from TVHE server.

Recordings stutter for reasons i can't ascertain.

Recordings playing back on TVHE server work well i.e. local client points to 127.0.0.1.

I can download the file from the NAS at 15-20mbps from server site to remote site. A recording of 30 mins take 10 mins to download. Once downloaded from NAS to PC on remote site it plays perfectly; therefore doesn't appear to be NAS or network.

Any suggestions on how i diagnose. Worked well until a couple of weeks ago.

Cheers, Geoff.

Remote Site: OSMC 4.4.18
Server Site: OSMC TVHE 4.2.8
