I'm attempting to use a CFF file for a Marantz SR-18 receiver to extract the appropriate IR codes to use with ORDesktop and Omniremote to program a MX-500 with the codes missing from it's pregrogrammed database. The original Marantz remote is history so learning is not an option. When I extract an IR code into ORDesktop it looks like this:
00005001 00000073 00000000 00000002 00000010 00000000
0000000A 00000000
but will not work, either using my Palm or by using my Palm to teach the MX-500. However when I teach the Palm a function that works using the MX-500 the IR code in ORDesktop looks like this:
00013240 01FE03FC 0FF03FFF 80FE03F8 0FF03FC0 FF0007F8
0FFFC07F 80000000 00000000 00000000 00000000 00000000
00000000 00000000 00000000 00000000 00000000 00000000
00000000 00000000 00000000 00000000 00000000 00000000
00000000 00000000 00000000 00000000 00000000 00000FF0
1FC07F01 FFFC0FF0 3FC07F01 FC07F800 3FC0FFFE 03F80000
00000000 00000000 00000000 00000000 00000000 00000000
00000000 00000000 00000000 00000000 00000000 00000000
00000000 00000000 00000000 00000000 00000000 00000000
00000000 00000000 00000000 00000000 7F81FE07 F80FFFC0
7F01FE07 F81FE07F 8001FE07 FFF03FC0 00000000 00000000
00000000 00000000 00000000 00000000 00000000 00000000
00000000 00000000 00000000 00000000 00000000 00000000
00000000 00000000 00000000 00000000 00000000
I don't know if the above is due to extraneous info or if all that data is actually needed. Anyone have any ideas?

This is speculation but it looks like ORDesktop only knows how to handle learned CCF codes.
The first octet in the long code is the frequency * 2 or 39200Hz.
The rest is a bitmap image of the code with each binary 1 representing carrier present for XXXµS and each binary 0 representing no carrier for XXXµS.
I no longer have my Visor/OmniRemote but from some PDB files I converted from CCF codes when I did have it, I think each bit represents ~5 cycles of carrier. You can probably clarify this on the Pacific Neo-Tek forum. If I'm right, 01FE03FC expands to binary 0000 0001 1111 1110 0000 0011 1111 1100 which would be a 200µS pulse followed by a 179µS space, etc.
What you have looks like three repeats with lengthy gaps between each code.
