Did you ever manage to get any reliable way prior to the CCP modules and the 18F2431 ?
Yeah - I used a USBee SX PC logic analyzer...;o) The 2431 approach is a lot faster, and gives me data I can print to text. I fiddled with one version that would even write PBP code for me to re-generate the same IR signals.

Steve,

Looks like a handy gadget. Should be pretty easy to write code with the data that spits-out.
