I have learned the value of researching any product you are going to buy, but more importantly, what it means exactly. My Samsung HS1000 home theater DVD player only outputs thru HDMI. My Samsung 5685 TV does not have a dolby decoder, therefore, you have to use the home theater speakers unless the DVD audio has the option for PCM output or the DVD was manufactured iusing PCM (not likely). When I checked the music DVD that was playing thru my 5685 speakers, there was an audio setting for either 5.1 dolby or PCM. When I changed it to dolby, I lost the audio.
Many thanks to Crown Audio in Lake Mary, FL for this information.
