Everything should be on the defaults except:
Kodi Recordings Folder = your smb share
ffmpeg exe = your ffmpeg location

Did you make a new recording after you changed the folder location?
Does it still reliably record to the default temp folder?  

Yes I made a new recording. When I look directly on the server in the folder, dann there is a json file, but I cannot see this file under recordings, there I only can see the folder of the serie.

 Try 0.0.85.
It was using the wrong recording path. The ffmpeg recording path if you turn off the pipe setting.
@maiers12 see if this fixes your problem too.

I'm going to blame our new kittens for sitting on my keyboard all the time.

Now it works, thank you very much for your effort. I didn’t understand very well yor last sentence about the kittens, but now take a rest from he keyboard.
Thank you again
