The pronto works terrific, and has for some time. However, we just moved the equipment into a cradenza with wooden doors (as opposed to glass) and my wife doesn't like me opening them every time I use the system. So, I want to use an IR distribution block ([Link: smarthome.com]). Works great on all my Denon and Pioneer Elite equipment. However, cannot get the Directv HR22 or the Polk XM tuner to work. Apparently, the unit I have picks up IR signals between 30-60khz and the HR22 and XM tuner may work at frequencies between 60-100khz. If so, I just need to swap out the unit I purchased. But, it's a $150 piece and with UPS costs back and forth, I'd rather nail it down before ordering another kit.

Here is a sample hex string for the XM tuner:

5000 0000 0000 0001 001B 004C

Cannot post one for the DVR as I used the database codes for all functions. None needed to be learned.
