My parents recently bought a 43" Hitachi RPTV, and I'm thinking about getting them a progressive-scan DVD player for Christmas. They're currently using an older, cheapie Toshiba model. According to the manual, the Hitachi set has 3:2 pulldown support. So my question is, is there any benefit to buying them a progressive DVD player? Or would the TV set's line doubler give them similar quality from an interlaced DVD player using component inputs?
