If you need any help regarding decoding codes, and if you have not already had a look, download the various files in the files section, Pronto /Pronto Pro section, Progs and Docs section, User docs section. Also get some of the utilities from the ccf uitils section. Just ahve a play, learning as you go. Barry Gordons article is excellent.

The best place for help for this subject (Hex decoding etc) is in the Philips Pronto And Marantz forum
