Does anyone have info on the Phillips RC6 coding scheme

I'm trying to help someone out who wants to create a 2-way IR file for a Phillips DVD730 DVD player. The remote appears to put out a newer Phillips coding format than what I have in the phillipsir.cde device file. I think it might be what is referred to as the RC6 format. Does anyone have info on this? I think the Pronto has built in support for it. If I can find out more about it, I can make this new device file or possibly change the server code to support it, if necessary.
