Good question, but I think it belongs in the forum of the prontos. Our PDA's software only read the ccf's. I use pdawin on my toshiba to read multible ccf's. I use Pronto edit to create my ccf's, utilizing other users graphics. What I am discovering is dirty code.
I have only been using this for x-10 stuff and am about to embark on my own home thearter set up.
To add to your question, is there a source by device manfacturer that will supply the actual codes and not other users interprted codes?
