HD Channels stutter (TVButler, DVBLink, Synology)

[syndvb]

With my setup I can watch SD Channels in expected quality but HD channels (ARD HD, ZDF HD) shutter (in German "ruckeln").

My setup.

Synology NAS DS213J
TVButler connected to the USB Port of the Synology NAS with DVB-C (Unitymedia)
DVBSource on Synlogy
DVBLink App on Android Tablet

Any advice how this could be resolved? Thanks.

Hard to pinpoint the issue from the information given but its worth looking at:

-NAS CPU Usage and resource monitors (check for multitasking, tasks scheduled etc)
-If using WiFi could be bandwidth issue - I would recommend gigabit cable from server to client
-Client performance issues (for example my Minix X8H-Plus/Kodi couldn't handle playback during multitasking)

Would be nice if there was a log to diagnose the bottleneck but I can't think of any.

Good Luck
