Hi, I'm new to home theater and all I have is a TV. My first purchase is going to be a DVD player(and then receiver and speakers, etc). Here's my question. How much better is progressive scan going to be. I have a tight budget and I can either get a Sony DVP-NS300 or a Panasonic RV-31 for right around $160. The cheapest I've seen the Panasonic RP-56 is a little more than $200. Is the addition of progressive scan worth the money? Should I save it and buy some good cables? Any and all help is appreciated.
