Thanks all. I tried to reinstal Kodi on OSMC and after that succeeded in manual connection of my video folder. As per the advice I did not select it is “films” and stopped serching the library and it really showed all files just in folders and +/- played them as you said. However, with a lot of lags, corrupted sound etc. for all HD videos. As I read in many places, it happens with high bitrate videos, so as per the advice I tried to mount the drive and did not succeed…
I grabbed the log here:

I did all setting in my Synology NAS as per KODI Wiki:
I tried to mount the NFS folder as per the guide: Configuring fstab based NFS share mounts
but still I get: -bash: cd: /mnt/VideoNFS: Permission denied
Please any tips what I am doing wrong?
