    Dolby Digital is not the HD Audio that you would want from Blu-Ray. The advanced formats like DTS-HD Master Audio, Dolby TrueHD or even LPCM (lossless compression) are not allowed unless the entire audio path is 'Protected'. That basically means HDMI and/or analog connections. Even if that were not a requirement the bandwidth of the optical used in DD doesn't have enough bandwidth to support the HD Audio...

    Basically what this guy said and what I said before. BluRay HD audio *REQUIRES* HDCP, not only because of licensing agreements with the content providers, but also for technical reason.

    Dolby Digital Plus (BluRay audio) is typically around 7.1 channels at 1.5Mbps.

    What's output over the optical port is downgraded Dolby Digital 5.1 which is 5.1 channels at 640Kbps.

    Hey, if you want to listen to only 50% of your audio, knock yourself out :).

    Sorry im late. Samsung PN60F8500 3D Plasma HDTV.

    Like most HDTVs, the Samsung does not pass HDMI-fed Dolby Digital or DTS signals from its TosLink audio output but rather converts them to two-channel PCM—a limitation for getting the most out of some outboard soundbars.

    If you expect to connect a soundbar and have the TV perform switching among HDMI sources such as a cable box and Blu-ray player, be advised that the ST’s optical digital audio output you’ll use to feed the soundbar downconverts all multichannel Dolby Digital and DTS bitstreams to PCM stereo, which will bypass any DD or DTS decoder built into the soundbar and result in less-than-best sound quality. This practice is unfortunately common to most HDTVs today.


    Think twice about sending audio through your tv folks.
    Only hometheater.com reviews reveal this. Most reviews
    don't discuss audio or just mention the built in speaker performance.

    This does not refer to HDCP, like you mentioned, which is not
