Does higher I/R frequences cause more data to be
stored? IE there are several products out there that
use higher frequences and can not be programmed by
lower/cheaper remotes. I do know that the Sony will
program codes for my Bang & Olufsen stereo (a higher
frequency remote, I can control it from another room
depending upon my position), but does it make a
difference with having higher frequency codes stored
in running out of memory?

I'm not sure - I do know that some brands eat up space faster than others (Panasonic vs. Hitachi). Perhaps someone else can clarify.

I've noticed that when programming buttons for a Sony device, that it takes half to a third of the time as programming either my Samsung TV or VCR, or my General Instruments cable box.

I don't know if that helps, but it leads me to believe that the signals may be of different bandwidths.
