Thanks for all responses.
Snofun3, is the quality of HDMI's audio signal higher than the standard coaxial digital output? I am well aware that technology of high-resolution displays is moving in such a rapid pace. My display projector bought new 3 years back is now an obsolete piece without any HDMI input, and not to mention that I have not changed the bulbs yet even until today, and now there's HDMI1.3? Oh jeez.
