I have two of these Vizio TVs.  Both have a pair of HDMI inputs, and
fortunately HDMI #2 also has a separate audio input in the form of the
red and white RCA plugs.  This is what I have been using for now, but
I am trying to minimize the number of wires by using audio over HDMI.
So adding DVI into the mix won't really help, unless somehow the DVI
carries the audio and at the same time doesn't carry the HDCP.
