or HDMI cables for a blu-ray? I have a 5 year old Hitachi 1080i TV. The instructions that came with it says it has a DVI connection. I never bothered looking for it until today, when I wanted to hook up my new Blu-Ray DVD player. Is there going to be a big difference in the picture I'll get if I use component cables (red, green, and blue) compared to a TV that has an HDMI hookup. I don't want to get a new TV because this one is in great shape, but I'm debating whether or not to take advantage of some of the Christmas time sales to buy a new one if it will be much better picture quality.
