Can't seem to learn a few codes?

Have my USB-UIRT working like a charm, now that I've learned how Girder and Sage interact. I have it grabbing the codes from my replay remote, transmitting channel changes, all that good stuff.
But no matter what I do, I simply cannot teach it the codes for volume changing my pioneer receiver. It gets about 80% of the way through learning in Girder, and then just sits there, lights flashing, but not getting that last 10/20% of the bar filled up. I have succesfully taught Girder at least 50 other codes from other different remotes with no problems.
It seems like its a standard remote, I have the 56hz enhanced version (thank goodness, otherwise my cable box wouldnt be working). I have tried learning in raw mode, but that didnt seem to help,
Any suggestions?
