IR codeset databases

Is there a reference database available anywhere on the Internet which allows a user to discover which IR codeset is being used in a certain model of AV electronic device ?

eg. Pace Sky+ digibox : Codeset = xxxx

and so on ?

This would be useful information to have available. Most of the learning remotes, eg. Prontos, have built-in databases but they don't tend to match up a codeset with an actual manufacturers branded product model.
