I have a Hitachi 61" rptv and am finally going to upgrade my dvd player to progressive scan. Are some progressive scan dvd players better than others ?(i.e. better methods for going from 24 fps to 60 fps, better 3:2 pulldown methods etc) or do they all do the same thing? In other words, if I see 2 dvd players very close in price, is there anything I should be keying in on as far as the description of the progressive scan capabilities? I don't want to miss any key info. I've been reading up on it, but I just want to make sure with the experts. Thanks.
