Pioneer Pro 520HD CRT Projection Question...Anybody??

[mzo0163]

I have had this tv for about 6 years now give or take and have a pioneer elite dvd player to go along with it. The picture from the elite dvd player looks fantastic and could be mistaken for HD at times even though its only 480p. I tried hooking up a sony blu ray player via the component out and I barely noticed much difference between the blu ray player and my elite dvd player. My question is could the VGA input on my tv possibly be used to hook up to the blu ray player and would that give me a better picture than using the component out from the blu ray player. I realize that the blu ray players do not have a VGA out, but is there any adapters that could be used and would it be worth it. Any input would be greatly appreciated, THANKS.
