Hey guys, I just bought the HD-DVD add-on from someone who showed me the thing in action and it worked perfectly fine. However, when I brought it home and hooked it up to my system, I seem to be having an issue with the Dolby Digital output. Everything is coming through as DTS! even if I select the "Dolby Digital 5.1" track. Here's my setup: Xbox 360 HD-DVD Add-on Xbox 360 Pro (w/ HDMI out) Onkyo TX-SR 605 (Black) Everything is connected via HDMI. So Xbox 360 -> Onkyo via HDMI -> Onkyo to Video Source via HDMI. Any suggestions?
