Hey Daniel
Great idea on this new forum!! I tried every code on the AUX device with my 15-2103 in order to find a discrete bypass for my Carver dd-5.1 processor. This would allow full 5.1 bypass for my dvd audio. None of the codes even powered off the processor. I like others would like to learn these to my MX-500. Now this brings me to a few questions:

1) Would I have better luck with a 15-1994 / Cinema 7 or are the codes basically the same as the 15-2103??

2) I found some codes that work most of the functions (bypass excluded) from the HTM audio tables. Is there any correlation from these to the four digit codes on other remotes?? This might help in my search?

3) If I would like to try some of the CCF files on this sight- Do I need a Pronto, or can I transfer these somehow into the above mentioned remotes??
Sorry for so many questions but I am new to all of this..
Mike
