Random IR Code Generator?

I just got a USBUIRT, and I'm loving what it can do with Girder!
Here's what I'm trying to do:
Get my Harmony remote to control my HTPC. I've got SageTV under control, but foobar2000 and the PC(mouse) emulation on the Harmony remote is givign me some trouble.
Here's the problem:
Finding IR codes to use for the HTPC and foobar2000. No exact fits exist in the Harmony database, so I've been trying to use similar devices and simply remap the commands using Girder. But many of the codes that I've grabbed (at random) from the Harmony site are RC5(?).
My question:
What strategy would you recommend for solving this problem? Is there an application that will generate random IR codes through the USBUIRT so that I can free myself from Harmony's database? Maybe even a random Pronto format code generator?
Thanks,
Steve
