Item Type
The following are special item types.
EPG This indicates that the schedule item has been added by Auto-Add. As such, this item may be modified or deleted in the next Auto-Add Scan, unless it is edited by the user (e.g. duration changed).

Adding a schedule from an EPG item and setting its type to EPG affects Auto-Add Scan; adding a blank schedule and setting its type to EPG does not affect Auto-Add Scan.

Auto-Add Scan does not add a new schedule if it overlaps (partial or full) an existing modified schedule with type EPG that was created from an EPG item of same start time and duration. This allows the user to increase or decrease the duration of an Auto-Add schedule without a duplicate being created in the next Auto-Add Scan.
EPG Scan Daily EPG scan, except that if an internal EPG scan has just been done the schedule may be skipped, determined by the "older than _ hours" field in Data Source Settings.
