My info tells me that neither Pronto nor IRIQ have the capability to learn the high ferquency codes of the Pioneer Elite "era of nonsense." Pioneer only did this silliness for one year and after taking excessive heat from the custom installation community, reverted "back to reality". If a Philips engineer advised that they may have a fix in the future, then I would suspect this is true. In the meantime, my understanding of the problem is more of a learning capability rather than the ability to produce once learned. The fix may come from the ability to download prelearned files to enable Pronto to create IR output from these files. Further, it is my belief that the disemination of learned files will become more and more commonplace as the population of Prontos increases. This is only my oppinion although it is based on what I know about the internal workings of Pronto and the ProntoEdit software.
