My audio receiver doesn't do True HD audio, but it does have HDMI input/output and can only do DD 5.1 or lower. After looking up articles around the net it seems I need an optical cable to output DD 5.1 for Blu Ray movies.
My PS3 games and dvd's switch in to DD 5.1 automatically, but Blu Ray movies only do Pro Logic 2 OR True HD audio with HDMI? Is that right? If so, that's totally messed up.
