Hi Thank you for that info. Unfortunately, I do not have the .2mm variety, so I cannot use the HD621. Since I cannot use the HDMI for Audio, I will need to use the single 75 ohm digital connection to my 568. What does my plain-jane 568 do with Dolby HD and DTS HD when connected in 75 ohm digital? Do I get Dolby HD or DTS HD at my speakers?
