I've just been connected to Telewest's (UK) Active Digital service and have tried to learn the codes from the remote for the set top box (Pace D1000T). The Pronto learns the codes without any errors, however they do not work.

Could the frequency of the codes be too high for the Pronto? Is there anything I can do? This is a new box so there probably won't be any ccf's to download for quite a while.

Please help, I was just getting so used to using only one remote instead of five, now I'm back to multiple remotes.
