Geo,

Once a HEX code for a given command on a given remote is available, it can be entered into Pronto via ProntoEdit accordingly via HEX entries.
There will be a site for end users to obtain these codes although probably not Philips due to legal and marketing limitations.
The best way for one to "get" these codes will be via a .CCF file (config file) and the ProntoEdit software as two CCF's can be merged within ProntoEdit then loaded into Pronto.
Suffuce it to say that such a web site will soon be available, I will advise when I know the specific date.....very soon.
I hope this helps.
