Hallo Ich habe ein Problem:
Plex läuft auf einem lokalen Windows Server, die Medien sind auf lokalen HDD:
Zum einen werden bei einzelnen Videos die Video Preview Thumnails nicht generiert er lädt bei einem Film eine weile danach überspringt er diesen

Beim nächsten Scan dass selbe, wenn ich den Film dann via Plex Webapp abspielen will (Maximum/Directstream) dann startet er den Film auch nicht…
Nur wenn ich bei der Quali “automatisch konvertieren” klicke beginnt der Film.
Das Problem habe ich bei circa 5 % von meinem Archiv.
Habe dann mal die Logs angeschaut und gesehen das es da einige Warns/Errors gibt mit denen ich aber leider nicht viel anfangen kann 
hoffe hier kann mir jemand helfen
