I ordered the XPL3000, yesterday and should receive it in probably a week from WorldWide but I just been reading about the HDMI-2 this box uses. The question I ask will this box still work with my existing Sony STR-DG710 AV receiver, surround sound system connected through HDMI. Or will I have to upgrade my surround AV receiver to another newer AV receiver that recognizes Dolby digital plus (DD+}. I think my existing Sony surround sound AV receiver HDMI ports recognizes Dolby Digital 5.1. Or am I thinking totally wrong about this?
