I have an LG upconverting DVD player and noticed that my LG TV is identifying a 480i signal being sent to it. The quality of the DVD picture isn't that impressive. I'm trying to view the DVD on an LG 42" HDTV. I read a lot of reviews on different upconverting DVD players and people are really impressed by the picture they are seeing? I tried hooking the DVD player to both the HDMI and component hookup but Ireally can't see much of a difference? I called LG customer service and the tech explained to me that the quality is dependant upon the quality of the DVD that I"m watching. He stated something that if the DVD was preformated at 480 quality that I might not see that much of a difference. I tried other DVD's and having the same results, even with newer DVD"s. Does this logic make any sense because it doesn't sound from what the tech told me that DVD"s can't upconvert beyond the native format. I guess I"m curious if you can really see a difference with upconverting DVD players since I haven't had a good experience with mine regardless of the positive reviews it got on a few sites.
