Because of that 330 in the timeout, I can add any digit I want to as the last digit and then pad out the timing, but what can I do with that last digit to fix things up? with those menu arrow keys. Apparently those are very important to the projector, since the one projector really didn't have much more than the arrows.

I thought about using 2001 (81) for the first fixed bit, and then if the last 330 thingy is 1,2 or,3 I'd change that first fixed byte to 83. Do I still use 5 byte commands then, or is there something else I can do to minimize the number of bytes I need include for the function? I noticed that when it starts 2003, the 5th byte is always 00.

I've just added some color to my previous post to show where the variable data is. The 2 least significant digits are always variable, so those can remain in place. The next 5 digits are variable, and for the arrows they change position. So, if you're using 2 variable bytes, that leaves 1 2-bit digit available for you to play with. So how about this...

If the control digit is set to 0, leave the signal "as is" because it's one of the main buttons.

For any other value, reduce the leadout time, overlay the fixed data with "20031021" and zero out the rest of the data (except for the last 2 digits).

If the control digit is 1, move the top 4 variable digits (including the 1) to the red spot for the OKAY and ESCAPE buttons.

If the control digit is 2, move the 5 variable digits to the red spot for the arrows.

NOTE: Can we try to find out why the LEFT button is different for the two boxes? If both boxes respond to the "TV" version of the button, that would simplify things.
