The HDMI audio output is often better than the standard coax output, depending on your processor. A realy high-end processor will be getting the best and most original digital information from your DVD and HDMI is the direction most of the letest releases are going.
If you have not invested in a high end processor then just stick with your DVI and coax, which for the time being is what I am doing.
