Depends on what you're trying to achieve.

Your Loewe most likely has an internal line doubler that takes your DVD's 480i signal and doubles it to be displayed in 480p. You're getting to see a better picture than non-line-doubled; however, chances are that the Loewe doubler is not necessarily the best.

You can substitute an outboard doubler (assuming the Loewe has an input that accepts a 31.5kHz scanning frequency, which I think it must to accept progressive DVD). There are many outboard doublers to choose from, ranging in price from $600.00 to $20,000.00. Even the $600 version will probably improve upon your internal doubler to a degree.

Most progressive scan DVD players simply include a higher quality doubler that operates in the analog domain as part of their circuitry; this is good--less cables, less distance for the original signal to pick up noise, etc.

Some progressive scan DVD players doube in the digital domain. This will yield the best result. The new Mits player just got a rave review in SGHT, it doubles in the digital domain, and for list 775.00, looks like a winner.

It all depends on what level of picture quality you're trying to achieve. I notice a difference between an outboard doubler and my set's internal doubler. The outboard doubler wins in red saturation and handling complex geometry. But not enough for *me* to justify a 600.00 outlay. Maybe I'll notice a big enough difference with the Mits player to justify it.

The little voices told me to get back to work.
