jdougan,

Don't know if you're still in need, but if so I highly recommend this product:

http://store.homeseer.com/store/GC-IRL---Infrared-Learner-Global-Cache-P539C47.aspx

This IR Learner is available from Homeseer for about $78.  It might be a bit pricey for just duplicating 3 button codes, but I have used it with great success to capture/duplicate IR codes.  One of the cool things about it is you can capture your generated IR codes and quantitatively compare them with the originals.  The IR Learner will give you output such as:

sendir,2:1,2,56000,1,1,23,345,23,158,23,94,23,158,23,158,23,94,23,158,23,158,23,158,23,158,23,158,23,158,23,158,23,158,23,158,23,158,23,158,23,345,23,158,23,94,23,158,23,158,23,94,23,158,23,158,23,158,23,158,23,158,23,158,23,158,23,158,23,158,23,158,23,158,23,345,23,158,23,94,23,158,23,158,23,94,23,158,23,158,23,158,23,158,23,158,23,158,23,158,23,158,23,158,23,158,23,158,23,345,23,158,23,94,23,158,23,158,23,94,23,158,23,158,23,158,23,158,23,158,23,158,23,158,23,158,23,158,23,158,23,158,23,345,23,1120

"56000" is the modulation frequency, the first "23" means 23 cycles of 56K carrier, then "345" means 345 cycles of no carrier, with further alternation of on/off carrier.

The IR Learner has a claimed carrier frequency range of 30 to 500 KHz.  It is DB9 serial, but I have used it with no problem with an Airlink USB-Serial adapter. 

An easy way to get started is generate a short on/off pulse train of carrier and capture it with the Learner.  Be aware the the Learner probably does not see visible light LEDs (i.e. use IR LED), and needs to see light that looks like a modulated carrier before it will capture it.  Also be aware it can be tricky to duplicate the range of IR remotes.  Try your IR code up-close at first; once you get it working move back to find the usable range
