I have uploaded a PCF file to the Remote Central forum that contains discrete codes for the Denon AVR-4306 made from the IR codes in the Denon document as well as MakeHex and IR Code Generator. The file hasn't been posted yet, but can be found over at the AVSForum here:
[Link: avsforum.com]. The pcf file contains a device, Denon 4306, that contains several pages named "IR XXXX", where "XXXX" are various functions (sone 2, tuner, etc). The discrete codes have all been taught onto those pages. I've encoded all of the IR commands except for the ipod control codes. I'll get to those once my iPod to Denon cable arrives....
