Binary code is representative of pulses and pulse widths of a signal... usually transmitted on top of a carrier frequency. Find out what denon considers 0 and 1. An example would be \x80 for 1 and [nul] for 0. Different manufacturers use different standards. Some will actaully translate a single hexidecimal byte into 2 binary bytes. Try converting binary (4 bits) directly into hex and then use one of the various pronto utilities to convert it into a .ccf file. I don't know if Via can use these .ccf files directly, but there must be another utility out there that will do the appropriate conversion if they do not accept .ccf files.

There is actually a pretty decent faq on ir signals on the website that you should check out.
