Buffer / Advancedsettings.xml / Play network-video without reloading

I have a playlist playing currently only one video.
The source is a “smb://” network source.

The video buffer cleares each time the same video starts playing.
I already set the following settings in the advancedsettings.xml (.kodi/userdata/)


(I have it once in <cache> and once in <network> b/c I wasn’t sure which one is correct)

I want the video to buffer on SD-Card and repeat the playlist. If there is enough space on the sd-card if should NOT reload everything from the network source.

So is there any hint on how to accomplish the task?
