The Producer 8 is an upgradeable remote, but to get the upgrades you need to send it in and they will return it with the codes for your devices added. The normal procedure is to call first and get a tag number for your transaction, then you send in the remote to their Ohio address.
Seeing as your over there in Blighty, maybe you could try contacting the UK branch of OFA and see of they will upgrade the remote for you.
Their address is:One For All (UK) Ltd,
P.O. Box 5363,
Northampton,
NN5 5YN
Their phone number is: 0808-100 0306
Their email address is: [email protected]If they can't help you, you only other option would be to call long distance to the States, using the number in your manual, and return it here.
