Yeah, that's what I currently do now for HD audio between the 3910 and the 3806, but I was hoping to expand my options to receivers or pre/pros that did not have DenonLink (which works just fine, BTW). I haven't added an HD audio/video source to my system yet, but I will keep your tip in mind when I do. Since the price of two HD units, one for each format (HD DVD and Blu-Ray) is cheaper than an upgraded rx or pre/pro, maybe that is the better option. Of course, that gives me a new problem, that of where to put all the boxes! Thanks for the info.
