I have been looking at two Samsung TVs, the 30'' Widescreen and the 27'' standard, both high definition. Anyways, is a DVI input important? These only have component video inputs. Somebody told me that TVs without a DVI will become useless because future formats like HD-DVD will not work on these two TVs. Is that true? I will only be using this TV for about 3-4 years until I get out of college and can afford something better.
