Not a dev so don't know if they can catch these episodes that have no SeriesName and exclude them or log them as the problem With some google foo and trial and error this should tell you the problem items.  As it provided the specific Series Items that broke my test setups. @Karpana Shut down Emby and made a copy of library.db to explore and see things without breaking the working db. select Path, Name, SeriesName, ProviderIds from MediaItems where type=8 and SeriesName is null
