These three points are from Widescreen Review. Progressive scan is more than just line doubling information. You may be satisfied with line doubling only and it will save you some trouble if you are. However here is why progressive scanning is used in dvd players/1: A dvd that is material from a film holds all of the information needed for and accurate progressive image. Any external doubler (whether built into the tv or not} must take hints from the analog signal for frame allocatiion 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 in-tv-doubler, must take a signal has come from one digital to analog coversion 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 variety of Ntsc sources, and their chosen settings are not always ideal for dvd. I forget all of the other articles on the subject. I am pretty sure Widescreen Review had done detailed articles on the subject. So the answer to your orginal question is really,no. You currently are not viewing progressive scan but rather line doubled interlaced which is close but not entirely the same. From what I have seen there is an improvement but not a tremendous one. But with videophiles, small differences to some can be tremendous differences with with them. Personally, I do not care that much for tv or movies and enjoy music. But I do know the answer to the question. Try it and see if it is worth it too you. It may be. You have a very high-end tv and a true progressive signal may bring it too the next level. Try Msb and that way you will not have to buy a new dvd player if you decide to try progressive scan.
