I have a huge list of training videos along with my reg movies
would like to fix metadata as now they show up with weird names
all reg movies are OK
an some how need serviio to ignore my training vids

If possible, put your Training Videos into a separate folder (not a subfolder of one that is shared). In Serviio console share that folder, unticking the "Retrieve Descriptive Metadata" option when sharing. Save and refresh your library... should give you what you need.
