Is it worth getting a dedicated DVD player when I already have an Xbox and a Playstation 2? I have my heart set on a Pioneer DV550 (which got 5 star reviews from the press). I'm currently using a Panasonic 32" TXPL10 Widescreen TV, am I likely to see much difference in picture/sound quality between this DVD player and, say, my Xbox which is currently connected via RGB scart? Sorry if this topic has been covered to death before! Thanks for any advice.
