With coaxial and optical inputs, the options are limited to DD bitstream, DTS bitstream, and PCM stereo - which, of course, works for just about everything except Blu-ray. Of course, without HDMI switching to allow the video to pass through, the only sources that could feed audio to the soundbar using HDMI and still get video to the display would be a handful of dual-HDMI Blu-ray players. Such players are rare, even more rare than BD players with analog outputs. We need more specs before we fully pin down this unit's potential.
