I've been meaning to get a prog. scan player. Then I keep reading that the line doubler in my TN61X81 is so good that I may not see much of a difference with a prog.scan player. Is that true? My real needs are for a good player that'll play VCD's CD-R's and preferebly a multi disk changer. I can get a sony DVD player for free with the sony card points. Should I get the NS700P or a ES series non-prog scan DVDchanger? Pl. suggest. Thanks.
