Do I only need the ProntoEdit software to do this?
yes, but since there are many remotes that use CCF, and they are interchangeable, it is a good idea to install all the editing software (RAVEdid, ChadEdit, RCEdit, ProntoProEdit, ProntoEdit) with ProntoEdit the last program installed. That way if you see a ccf you like designed for a different remote, you can still convert it into a Pronto CCF. Also install PE last, so that it is the default program for CCFs on your PC (in the file section under remote it will tell you for what CCF using remote the CCF was designed to be used with.
I've got all of my components programmed into it, but
only on the default layouts. I'll probably try the
custom layouts after I get used to it.
good idea
Is it easy to pick through the downloaded files and
only use certain screens, layouts, etc?
once a decision is made yes, but there are so many CCFs out there that finding what you like is hard :-)
