Update:
Vito makes one that is compatible, but is also horrifyingly painful to work with: It has no .ccf support, but even worse, its only templates are 'TV' and 'VCR'. Anything with a different control set requires making your own buttons one by one (no copy, no paste) and naming them using an extremely limited set of predefined labels (to give you an idea, there are no directional arrows). If you want to use text, it has to be on a particularly garish rectangular two-toned button. If anyone has found an alternative to this program for the e750, please, please let us know about it. In the meantime, Vito's fine offering is functional, at least in the sense that you can learn and emit IR commands without crashing the PDA. License: $15
