Maybe give this a shot (a little wordy, but kind of hard to explain):

Quite a few years ago I was programming a remote from various other remotes.
All went well except for when I used the newly programmed remote to operate
a particular device.  The device would respond to the original remote but
not the programmed remote.  

The remote that was being programmed had an LED that would light whenever
you would teach it a command (confirming it had "learned" the command).  I
think most programmable remotes have this (at least ones I've seen).  This
LED lit for each command I taught it, including the commands from the remote
for this particular device.

A neat feature on this programmable remote, which I haven't seen on others,
is another LED which lights to indicate when it RECEIVES an IR signal.  What
I found from this is that the remote it was having a hard time learning from
was actually sending TWO signals from a single press of a button.  When I
pressed a button on the teaching remote, this LED would flicker before it
lit steadily (indicating two transmissions).

The learning remote was only picking up and learning the first transmission
(the LED flicker).  It was ignoring the second transmission (LED steadily
lit).  I eventually taught the programmable remote by pressing and holding
the button on the "teaching" remote while it was pointed away from the
learning remote, then, while still holding down the button, pointed it at
the learning remote.  The learning remote would then not "see" the first
transmission and would therefore be ready to see and learn the second
transmission.

It took me a while to realize this is what was going on; first I didn't
notice the initial flicker of the LED, and then when I did notice it, I
couldn't understand why the original remote would send out two signals for a
single button press.  In fact, you could point the original remote away from
the device, press and hold a button, and while holding the button, re-aim at
the device and the device would respond.  I finally taught the programmable
remote each command from the original that I wanted, by using the above
method.

Like I said, I did this a quite a few years ago, and never did figure out
(for sure) why this particular remote sent out two signals when the device
it was controlling appeared to only listen to the second signal.  The device
was either an old Sony dual cassette deck or a Sony CD changer.  Haven't had
this problem with other Sony's (or any other device for that matter).  This
is back when learning remotes were first becoming popular, and Sony was
selling replacement remotes for their products at high prices.  I kinda
figured this was their way of preventing people, who lost their remote, from
stealing remote codes from a friends' remote (and therefore forcing them to
buy a new one from Sony).

Might be worth a try.
