I've recently purchased a Panasonic 42 inch plasma HDTV I saw a cable package they were selling which included two HDMI cables along for about 80 dollars. I currently am using component cables and was wondering whether I should upgrade to HDMI or DVI for my screen. If I were to upgrade to HDMI would cable quality matter (i.e. should i purchase it from a more name brand company or are all cables pretty much standard). Thanks
