I've found the problem and the solution!
I also have a USB disk attached containing my UHD movies.
Last night I added a folder (skin backup) to that USB disk.
Apparently the files in that folder were mistakenly seen as movies and thus added to my library.
PEBKAC 
Yes, I've installed Backup and Keymapper and a subtitle (opensubtitles.org) addon.
I was just wondering if the dependencies from Horizon (skin) could be the problem.
Because I've installed all of those...
Yeah I did that in the past as well, but since libreelec is smart enough to read the correct names I no longer bothered.
Now al of the sudden this happens. And renaming the movies doesn't look like it is gonna solve this problem.
My library now sais I have 502 murder on flight, otter 501, 500 miles etc I have never even heard of these movies 
ls -la nfs://10.0.1.15/nfs/Media/Movies/ | paste
gives the following error:
ls: nfs://10.0.1.15/nfs/Media/Movies/: No such file or directory
Hi
They have various names.
eg The Fast and the Furious.mkv and The.green.mile(year)1080p.mkv etc.
I’ve used it that way allways. Bur now since a reinstall it makes up movies that I don’t have.
I’ve a NAS with a folder named Movies.
I’ve added that lovation as a source.
When I refresh the movie library it looks like all the movies that exist on the scraper are being added. Eg 112 113 and much more movies that I don’t own.
When I clean my library they disappear. But the next time I refresh they all come back.
Help!! It drives me crazy 😄
chewitt Thanks. Will give that a try.
It has been running fine. No issues whatsoever.
I also haven’t updated the bios or anything. It just died between boot cycles.
edit:
I fixed it by reinstalling.
Don't know what happened exactly, but two kids constantly asking to watch a movie made my choice of reinstalling somewhat easier.
Hi guys,
I've been running Libreelec for a while now on a Intel NUC with a SSD installed.
Today I shutdown the system and later when I repowered the unit it didn't boot anymore.
The error is :
*** Error in mount_storage: mount_common: Could not mount LABEL=Storage ***
### Starting debugging shell... type exit to quit ###
sh: can't access tty: job control turned off
#
Any help/suggestions?
Thanks in advance.
Arjan
