DOBLY DIGITAL AND D.T.S ARE BOTH 5.1. SOUND .All d.v.d. movies are incoded in dobly digital and if the movie is in d.d and d.t.s. the disk will default to d.d. and d.t.s. is an option Also d.t.s. sound is a little bit better than d.d. maimly all 5 channels will be at the same audio level . in closing I had a cheepe Sony player $100 which I gave away because of it horrrible picture and bought a Denon 2910 and the picture and sound are awsome
I just got a great deal on a Samsung DVD player (DVD-HD755) because there was no difference on the box descriptions between that one and the DVD-HD850. But then when I got home I learned the one I have may not support DTS. I paid $70 for this HDMI upconverting DVD player, while the DVD-HD850 sells for $150, so my question is how important is the DTS? I just got a new 44" Panasonic HDTV and am getting HDTV via Time Warner cable and am about to buy a surround sound system (probably Onkyo HT-S780 or some type of THX Onkyos system I piece together). If I have these systems, do I really need the DVD player to have DTS, won't the tv or receiver take care of that?
