When adding an entry to a category from the KMC to display in Kaltura MediaSpace, be certain to add the entry into either the Channels, Galleries, or unlisted category located under the SITE category.
Do not add content to both the unlisted category, and other categories. This will cause unexpected behavior.
We do not recommend adding entries to other categories under the MediaSpace root category, since adding entries to any other category, may create unexpected issues.
For information as a KMS user, see Publish Media in MediaSpace.
