You say it sounds great yet the dvd has no sound; so what sounds great?
I don't know how the connections are on your samsung but I had one where the input audio must be conneected to the same area as the components connection. Have you try making the tv audio output (MONITOR) connections to the a/v reciever, (if there is one available)?
i just got a Samsung HL-P5067W DLP TV. i hooked up my Sony DVD progressive scan player directly to it with a component video cable for the video and a standard patch cord for the audio. i then connected a patch cord from the TV's audio out jacks to my AV receiver's input jacks. the sound through my audio system is great except that, when i play DVDs, the TV does not send out any signal through the output jacks. i RTFM and it says, "Note: It is available only in RF, Video, and S-Video modes." what does that mean? that if i connected my DVD player to the TV with the composite or S-video cable, that i'd get audio output? if i used a Y-cable to split out the audio output of the DVD player and plug directly into my receiver, would sound quality suffer? thanks. very confused here.
