maybe I'm stupid?

i guess I don't understand Blu-Ray technology that well...I was looking at the blu-ray ad on ghostbusters dot com and wow the picture quality is even better than DVD - I guess a lot of people have said that, but I was viewing the ad on a SD computer screen, so I'd imagine even at 720p, my television would probably pick up an even better picture than what I saw on the ad at Sony's GB site.  plus I'd forgotten the packaging for the GHOSTBUSTERS Blu-ray is way better than any of the DVD pressings, and...well...I guess I might as well buy a Blu-Ray player when I get my Circuit Breaker check early next year.  I'll probably get $300++, so a Blu-Ray player will be a piece of cake...
