guys I have a ws-48413 tv and it has several hook ups. I have comcast high def cable. I was reading the manual and if I'm reading it right it says to use the dtv hook up, I currently have it hooked up via comp 1, will this make it any better of a pic. Also I was thinking about the dvi hook up but the one on the tv has the dvi-i connector and the cable box has the dvi-d connector. Any help would be great.
