Unfortunately I am unable to obtain your details via the forum at the moment. Please could you send me a PM with your address, postcode & telephone number & I will look into what is happening with the On Demand for you.
I cannot find a known outage for VOD at your specific location. Can you confirm that both your stb's are affected, and do either of them have flashing online\heartbeat light? Do you get a specific error message\number when trying to view anything?
