A Lecture Capture event may be owned by a group owner due to entitlement settings. This behavior is due to a backend constraint that does not carry out entitlements over 'scheduleEvent' objects. To ensure that users that have access to the calendar, have permissions to view/edit the entry that is connected to the event object, Kaltura places all the users that are allowed to access to the calendar in a group and sets the group as the owner of the entries. This ensures that if you can access the calendar, you can access and manage the scheduled events in the calendar.
