    I'm thinking of buying a new DVD player

    with a progressive scan output. I'll use

    the player's component output into my FPTV which has

    a built in line doubler.

    Will the scan be quadrupled (sp?) or what?

    How will the image be effected? Anybody know?

    Thanks,

    Dan

    If my memory serves, the line doubler in your DVD player will over ride the doubler in your set. I'm pretty sure this is right. If anyone knows for sure, let us know.

    Units with internal doublers (both front- and rear-view) automatically disengage the doubler when an incoming 480p signal is detected. Many of them upconvert 480p to something else for display, but that's a separate function and happens regardless of how the 480p is generated.

    Daniel, it might help if you specified the make and model of your FPTV.

    Michael,

    I have the Sony VPH-D50Q front projector

    with Sony's EXB-DS10 built-in line doubler

    board which I can manually turn on or off.

    I suppose I could have re-phrased the original

    post question to something like this........

    If I have a set with a built in line doubler,

    should I bother to spend the $$$ to upgrade

    to a progressive scan DVD player?

    I can't do a test if I don't buy and

    I won't buy if it's not going to make

    much of a difference to my system.

    The general consensus is that a p/s player will do better than a line doubler unless the doubler is one of the pricey scalers like a top-of-the-line Faroudja. Bear in mind that the p/s player, if it's properly designed, creates the 480p image entirely in the digital domain, whereas using a separate doubler involves additional digital/analog conversions.
    As to the degree of difference, that depends on the hardware and the sensibilities of the user.

    That's the answer I was looking for.

    Thanks Michael.
