--- Comment #10 from Alexander Wipperfürth <wpprfrth at posteo.de> ---
I don't have to imagine, I have thousands of video files on my drives, 
it's not cool that this doesn't work properly, I thought about some 
stuff we could do and this would be to fork dolphin and patch it so it 
doesn't regenerate the thumbnails and instead use the cached files 
instead, this would require searching through the code and identify 
where this is and we can build our own version of Dolphin, or someone 
from the dev team gets the same issue and gets tired of waiting for the 
previews to finish regenerate and patch it.

Currently I don't have the time to look into this very deeply but I will 
when I have some spare time and maybe we can somehow find a fix for this.
