That is going across continents.
To transfer the pulse coding of a remote control at one site to another
learnable type remote control maybe the other side of the world.
Can anyone think of a method that uses off the shelf equipment used in a
domestic environment , ie not using oscilloscopes etc.
Somehow slowing the pulse stream down enough to capture on cam-corder/pc
etc.
Would the average r/c with say a 400 KHz ceramic resonator still function
with the 400KHz one replaced with 100KHz one say.?

Look up LIRC (linux infrared remote control).

For example, I can type remotecontrol.p (a PERL program) on any computer
on my network, and the satellite receiver downstairs changes channels.
I can also control a VCR and Stereo Recevier.

If the remote control you want to duplicate is not listed, you need
to use a receiver to decipher the codes. You can make one yourself or
buy one for about $30.

The remote transmitter can be as simple as an IR LED and a resistor. Since
my equipment faces a window, instead of trying to make a unit bright enough
to overcome the sunlight streaming in, I just made three of them connected
to the same serial port and placed an LED next to each sensor.

The remote computer does not have to be much, it needs to run Linux,
have some sort of network connection and a serial port.
