Any experts on "Learning Remote Controls"?

Ok, let's say it's 100% an infared remote.
The problem here is, except for getting another learning remote and
trying that, I can't see where else you can go with this problem.
It's not like you can "fix" the RS remote to do anything differently.
Unrelated to this, back in the late 90's I bought a Yamaha surround
sound receiver, high end (something 3090) and also had a Phillips
touch screen remote (pronto) and that receiver was a bitch to program
into the remote.
It said it learned all the key presses I wanted it to learn but
****-all when you tried to use it. Besides some keys not working at
all (similar to your problem), others did not do what they were
supposed to do. Even like volume up, if you tapped the button it was
fine, press and hold would raise it to a certain point, then it would
decide to switch the input selected.
The on/off had a direct on, a direct off and "toggle". That too, the
toggle was fine to use but the directs for on and off was a crap
shoot.
What I'm getting at, being the remote was 100% with various tv's, dvd
players, vhs machine, laserdisc players and just had a headache with
the Yamaha, there really is no other fault besides it.
The OEM remote for the Yamaha had like 105 different functions, I'm
guess they used some creative coding for all that to fit.
Similar to your HD tuner, maybe the idea of IR having a problem in
such a place as a car, the company used some creative coding for it
to work where it doesn't follow the norm for remotes. I know that
back in the 80's there was supposed to be some standardization,
preamble with a max of 16 bits, padded zeroes at the end or beginning
that all companies were supposed to follow.
Was just to sort things out so the vcr remote didn't do anything to
the tv or the dvd remote turn on your microwave or something.
My point is, maybe since it was for automotive use, they didn't have
to follow the consumer guidelines for household products, figuring it
would be unlikely to have two IR devices in a car and just came up
with a IR pattern that worked in such a harsh environment.
Like I said at the beginning, the tie breaker is just get your hands
on another learning remote and see if it can learn anything. If not,
what you want to do is just not going to be done. If it does work,
it's the RS remote but then you are where you are now, it's just not
going to work and there isn't anything to do about it except replace
it.

Very good commentary. I should have other learning remotes, and will have to try
another. Thanks.
