Progressive/Line-Doubled...

A DVD player with a progressive output can be visualized as a regular DVD player with a "line doubler" built in. The terms "progressively scanned DVD" and "line doubled DVD" are one in the same.

If you have a progressive DVD player [with the progressive output turned on] you cannot use any other scan conversion device between the front-end and the monitor...unless the monitor in question is fairly unique, and has special needs.

Some/most HD monitors have a scan converter built in. They automatically up scan any incomming signal that is less than 480p, to 480p. If a signal at or above 480p is presented to the projector, it will automatically disable its own internal scaler [at least that's the most common way], and show the image in it's native resoloution. The output from a progressive DVD machine is 480p.

So now, the question is which device has the better scan converter? The DVD [front-end device] or the monitor. Typically with a cheaper front-end most folks will often prefer to use the interlaced componet outputs and let the monitor scan convert the image. With a high end DVD player, usually the onboard scan converter will look better. Best to try both and see. Frankly, in the $300 catagory, I wouldn't expect very great things from a DVD players scan converter. The DVD2800mkII is superior to the 900 both in terms of build and performance [audio and video].
