stream ist stumbling

[Hecktor]

I am not sure if the failure is the PVR addon. First I used openelec 5.02 with PVR 1.9.13

But after reinstalling openelec 5.02 the stream is stumbling the hole time. The CPU seems to be permanent at 100%. That is why I tried to reinstall a secound time a fresh openelec. But the same.

Than I installed raspbmc. After installing it works a moment. Than it is updating. After updating it is catched in a boot loop. The same after reinstalling.

Than I tried OSMC. The system works. CPU is normal. If just open the PVR addon the CPU is about 100%. If I open the recording overview it is 100%. If I try to play a stream it stumbling. With acitiveted transcoding the TV stream works. If I go back to the main menue the CPU becomes normal.

Do you think the stumbing is because of the load of the CPU?
