I'm setting up a new system. Samsung hln507w, yamaha rxv-1400, comast digital cable + hd, Samsung hd931 dvd. What is the best way to hook up? All thru receiver? DVI between dvd and monitor? Audio cable or optical? Component video cables? Type important? I have a 25' span between my monitor and rack set up now. If I wouldn't loose significant picture quality, I'd opt to keep every thing as is.
