After a few half hearted attempts I am now trying to put together a decent home theater system but find that I am a bit overwhelmed and need help with a few things. System consists of the following: Amp = Yamaha RX-V620 DVD = Panasonic RP-56 (progressive scan) TV = Hitachi 32” Ultravision HDTV Cable = Cox Digital cable box Speakers: Main = Definitive Technology SM450’s Center = Definitive Technology C/L/R/ 2000 (bi-wired) Surrounds = Bose Acoustimass 5 Series ll. (Will upgrade to Def. Tech. BP2X after woofer purchase) Woofer = Looking for recommendations (wife says it must be a box – considering Def Tech Super Cube 1 – but the new SVS box @ $600 has caught my attention. Setup: DVD connected to amp via optical cable Amp connected to HDTV via component out Cable box connected to HDTV directly Calibrated TV and Speakers using Sound & Vision “Home Theater Tune-Up” Used a Radio Shack SLM to calibrate speaker sound levels Problems: A) After hooking everything up I am not able to get the receiver to produce sound in the DTS setting. (works fine when set to automatic but defaults to Dolby) Not sure this is a big deal – but if I were missing a major benefit by not having DTS then I would want to fix this. B) How would I hook up my cable box to run through the amp and then back to the TV? I would really like to use the center channel speaker with the TV. C) Should I be able to set the system up once and leave it alone for both movies and CD’s? (When I play movies I seem to have to reset the speaker setting and center volume to get the best sound for each movie. When I play CD’s go through a similar drill. Thanks for reading this. Any help would be very much appreciated – as I said before, I am new to this but determined to do it right. Besides, it’s a lot of fun (just with the budget would allow me to purchase everything at once).
