Is the reason my HDVT (Comcast) picture quality looks better than DVD, because I'm viewing 1080i vs. 480p? How can I improved DVD PQ? It's not bad, just not as good as HDTV. I've got a new Panasonic TH-37PX60U, an older Sony DVD player, Comcast DVR - all connected via component cables through my Onkyo A/V receiver. Thanks for the help - still learning.
