The biggest issue I can see here is the action to take when Freeview programmes are selected. Currently, the Now TV Player is launched with the correct deeplink to start playback. However, Freeview playback would need to be launched differently - perhaps it's a plugin, or something else.

This may differ between users, so unless selection of Freeview programmes from the uEPG were a NOOP - which may lead to confusing UX - then I'm unsure what to do on selection.
