Which players are missing?
The following players will only be shown if your aerial is connected properly: All 4, the ITV Hub, STV (Scotland) or S4C (Wales).
If all of the above players are missing, this indicates a problem with your TV aerial or the aerial cable. Remove and reconnect the aerial cable on the back of your set top box, making sure it's connected securely when you do this. Finally, close and reload the On-Demand menu and the missing players should have returned.
In all other cases, follow the steps below.
