Silly question perhaps but what is the advantage of using HDMI with this unit? Does it affect the performance or abilities of the HR 20? I am currently using HDMI with my HR 20 and (knock on wood) have not had any problems. I have a new Sony DVD player/changer and I only have one HDMI port on my set. Unless I want to purchase a switch I am forced to choose between the HR20 and my up converting Sony DVD player/changer. If I go component on the DVD player it will not up convert.
