I have an S-Video cable hooked from my tv to my dvd player, but recently, i have noticed black lines blended into the black backgrounds of loading screens and sometimes during the movie itself. These vertical lines are only in dark black colors. Also, if a movie is in 5.1, are the sounds supposed to all sound the same, like explosions for example. I just bought Terminator 3 and the whole movie was a fantastic sound experience thats for sure, but like for example Rambo II, the explosions and other effects do not sound as rich or full as other movies in 5.1. Thanks for any info anyone can give me, I appreciate it.
