Rodney, I'm not familiar with the Emotiva stuff and haven't had a chance to study it for your question, but playing a DVD with DD audio doesn't use DPLII(or x)for a 5.1 speaker setup. The DPLII expands two channel CDs to 5 speakers, and DPLIIx further expands either two or five channel material to seven speakers(if present). So, for your 5.1 speaker setup no form of DPLII is used with DVDs for DD, just straight DD.

Enjoy the music, not the equipment.
