@3DBuff:

I had a problem once where i missed many of my movies out of nowhere. Emptying and rescanning the database didn't help.

Turned out that somehow a filter was set to only show watched movies...

 It seems that some Triggers where broken in the new Kodi Nightly.
Still can not change the InfoBar Type in my Live TV Mod Settings.
And all my Background Pictures in the Main Menu are gone. Also still got Problems while listen to Music. Sometimes it reboots out of the blue sometimes it hangs up without reboot. Switch back to 530 and all is fine. except the music.

Updated recently. Now my library only shows watched movies. Even if i set the filter to "show all" (or whatever it says in english).

Check your kodi log for errors, there's nothing we can do when you don't post a log. "Updated recently" also isn't very specific. If this is a database issue then go back to your old build and it should all work. Drop the latest MyVideos database, enable debug logging, repeat the upgrade to latest build then post the log if it contains migration errors. If there are no database errors then this problem is likely due to some other issue, in which case knowing the first build when the problem starts is valuable information.
