me and this guy were talking about home theater, his speakers and reciever cost less then $900 like sony satellites and a pioneer reciever or something, my speakers and reciever cost $2,000 Athena Audition setup with a Yamaha reciever but he went on about how my system was a piece of garbage cause he's like Guy: "you dont have digital sound" Me: "it says dolby digital on the reciever" Guy: "well do you have fiberwire?" Me: "i dont know" Guy: "then you dont have digital sound" Me: "what would happen if i dont have digital sound" Guy: "it's all just simulated sound, it's not true digital sound do you have DTS?" Me: "it has modes and has DTS and then Neo 6 and Pro Logic II, why what would happen if i put it on those modes without digital sound?" Guy: "they wont work, no sound will come out of the speakers" Me: "but it does" Guy: "well then i dont know" i just took what the best buy guy gave me, made sense out of them and hooked them up, i got 1 yellow red and white cord goin from the tv to the dvd player, i got a red and blue goin from the dvd player to the reciever and another red and blue cord goin from the dvd player to the reciever, i dont understand how the whole coax and optical thing works cause i read the primer and you still have to be a genius to make sense of any of that, i just kinda want to know what cords i need and how to hook it up to to get this mystical digital sound stuff, this happened a month ago but i didnt address the situation until now cause im not combfortable with what he said, up until like 2 weeks ago i watched movies on 6ch stereo, now i watch them on Pro Logic II, i cant tell if its doin what its suppose to do cause i dont have a good ear, if it is doin what it's supposed to be doin im not very impressed with the whole surround sound idea, but i dont think thats the case cause it sounds so cool at my friends house i might just be paranoid and dont notice it in my house cause i choose not to or something. Anyway, if someone could help, and explain like there talking to a 7 year old that would be awesome.
