Hello,
This question will be cross-posted in the Pronto, Pronto NG, and the Pros forum...

Denon posted the new discretes for the XM tuner and zone 3 that are 48 bit codes. The traditional 15 bit codes can be keyed into one of the many HEX creators here and elsewhere, but the length of this code will not allow us to find a suitable converter...

Here is the PDF of the protocol:

We have called Eric Johnson at URC, Damon at ProRemotes, and the guys at RTI... We are all stumped here and looking for a solution.

Any ideas??
