Timeshift stutters with simultaneous recording.

Hi Guys,

when I record an HD+ channel and at the same time watch a show with Timeshift on an other channel the picture stutters every 10s.

My system is a J3455-ITX with 4GB memory. The system partition is on an SSD. The recording and timeshift folders are on an 4TB harddisc.

I have Libreelec 5.1.2. My tuner is a DVD-S2 double card: DVBSky S952 V.

Is the J3455-ITX is not capable to record and timeshift at the same time?

Here is my log: hedG

I would appreciate any suggestions.
