    Most HDTV monitors incorporate internal line doublers that turn the 480i("i" is for interlaced) signal from a standard DVD player to either 480p("p" is for progressive) or 960i. Some of these TV's also incorporate 3:2 pulldown correction which greatly reduces jagged edges. A HDTV monitor with a "good" line doubler that incorporates 3:2 pulldown correction can look as good as direct feed from a progressive scan DVD player (which is already 480p). In fact, I tried several different 480p players with my Sony HDTV monitor and found the improvment over the TV's internal line doubler to be very subtle, and my TV doesn't do 3:2 pulldown correction (3:2 pulldown correction adjusts the frame rate of film on video). Progressive scan DVD players are not magic bullets and the only way to know whether you prefer a standard vs. progressive player on your particular TV is to try one.

    DVD: Panasonic RP91
    TV: Toshiba CW34XC2 (HDTV ready)
    The difference between progressive scan vs. linedoubled interlaced using this combo is definitely noticeable, but it's not a humungous difference. I'd be happy with a good interlaced source on this 34" widescreen TV, but I do prefer having the progressive source. However, things may get more noticeable on a 60" screen, depending on the abilities of the TV. YMMV.
