I was at a local high-end audio/video store wanting to buy a new DVD player. I was looking for a progressive scan DVD player because I plan on upgrading my T.V. soon and want to take advantage of the higher resolution. The salesman said that if my T.V. has progressive scan capability built-in, I wouldn't need it for the DVD player since the T.V.'s progressive scan unit would probably be superior to the DVD player's. Is this true or do I need a progressive scan DVD player AND a T.V. able to take advantage of it? Thanks.
