STV channels aren't on Stream in the 8000s though. It's only ITV owned regions.

Channel 3 regions are not on the EPG in the 900s. They are only available though the 'Add Channels' feature. STV ones can be added on other Sky services.

The only additional EPG listed C3 broadcasts are the national version of '+1' and I believe the one doing audio description, although that seems to have vanished.
