The pages on the ccf are well laid out for my use. The important part of this development is the IR codes that are available for the VSX-901S. These codes are very hard to come by but I have the original remtoe control so I have learned the majority of the codes and saved them in the Macro Group section of the ccf file. This should enable anyone who has the Reciever to create their own set with the codes that are no where else to be found on the web. Enjoy!
