I tried posting this but does not look like it did. Here is why it makes a difference. I got this information from Widesreen Review. 1:A dvd that is mastered from film holds all of the information needed for an accurate progressive image, any external doubler(whether built into the tv or not) must take hints from the analog input for frame allocation. 2:Since the signal form a dvd is digital, the progressive conversion can be performed digitally inside the player, perserving the signal quality up to the analog output. A stand alone, or in-tv doubler, must take a signal that has come from one digtal to analog conversion, then reconvert it to digital and then back to d/a for display. THIS CAUSES THE PICTURE TO DEGRADE. 3:Line doublers, either in-tv or external, must be able to work with a wide variety of NTSC sources, and their chosen settings are3 not always ideal for dvd. True progressive scan is different from just line doubling the signal in with your tv.
