I recently acquired a PBO Core, which is merely a rebranded version of the Box Office with updated labeling and firmware. I don't believe the IR protocols have changed from the earlier incarnation.

Since my B00 remote doesn't have the 0575, 1224 or 2185 device codes, is there a suggestion for one that will work?

I've tried using the PVR/DVD/VCR 2010 device code after reassigning it to the AUX device key and it won't respond.
