    Folks,
    I currently have a DVDO iScan Pro line doubler, mated with my Sony interlaced DVD player.
    I am considering upgrading to DVD-Audio in the shape of the new Toshiba SD4700. The SD4700, however, has progressive output.
    I do not know the quality of the internal line doubler of the SD4700, but I'm fairly sure that my iScan is probably better. If my assumptions are correct, how can I still use my iScan with the SD4700? I don't think the iScan takes in progressive signals, so is there normally a way to send out interlaced signals from progressive units?
    Any info greatly appreciated.

    On my RP91 you can just not turn the progressive switch on the front on.

    Jon,
    while iScan does a great job of line doubling, it introduces extra A/D-D/A conversion. I recommend you compare the 4700's progressive mode output -- it may be better (I assume you have either a wide-screen or squeeze-capable display).

    Not sure about that particular Toshiba unit, but I believe that *all* progressive DVD players have the option for interlaced output. If there are exceptions (I'm not aware of any), then they are extremely rare.
    You're probably right in this case that the iScan has a better line doubler than the Toshiba, though of course there are other DVD players that'll also have better de-interlacing than the Toshiba.
    In any case, you should be in good shape with what you're considering (unless your TV doesn't support anamorphic squeeze for 480p input, in which case I'd steer clear of Toshiba DVD players altogether.)

    Which Toshiba prog. dvd players don't have aspect ratio control, besides the ancient 5109?
    My 6200 does and the 9200 as well.

    Mark-
    I think Neil was referring to the anamorphic downconversion artifacts that Toshiba DVD players introduce.
