It isn't clear that recording IR with the camera is impossible.
At best it's going to take moderately significant effort to develop the software to do this.
(place IR remote against camera, press button, observe 'barcode'.)

hmm, interesting. Need to work out if the camera framerate is high enough to detect all the transitions in the IR signal.

AFAIK, IR emisors work on something around 40khz so I doubt a 25 FPS cam could read it correctly.

The 40kHz is a modulation frequency isn't it, like an AM signal? The rate of the data being sent is lower than that, but still too high for the camera to detect.
At ~30fps, each frame lasts something like 33ms (ignoring integration and reading times), and the bit length (in time) for e.g. a Sony remote control is of the order of 2* 600µS.
See http://users.telenet.be/davshomepage/sony.htm
So no chance anyway

anyone know how to record ir signal from remote to n900 i dont want to use any laptop in that << hahaha
i saw video to record with laptop and its long
i want any way to record the signal with n900 so i can make my own remote
and ty
