I'm now the happy owner of a Sony CRT (VPH-1000)! I've set it up in my living room (temporary, until I finish working on my basement and turning into a HT area), and I'm loving it! It's an older unit (manufactured in 1991 I believe), and is fully analog. There are no digital controls on it, so all tweaking & configuring had to be done manually. When I first took it home the picture was terrible, and I needed to open the unit up and play with the controls until properly tweaked (it took me a couple of days, but dear lord the picture looks MARVELOUS right now!). I popped in Shrek, and was blown away by the quality of the image. Even projected on my yellow walls (I've painted recently, so my white walls are gone) the image was rich & vivid, and dare I say it, looked better than I've seen it on my parents' LCD projector. My question is this - I've done some searching online & I've heard mentioned on Line Doublers. Now, I have a progressive scan DVD player, and I'm connected to the CRT via S-Video cable. Would a Line Doubler be of any use to me? What exactly does it do? Would it be useless with my progressive scan player, or would it improve the image? Any help would be appreciated! Thanks, Moe.
