P. Scan DVD Players and HDTV-ready TV's

I have a Loewe HDTV-ready TV with a 16:9 aspect ratio that has built-in progressive scan. I would like to upgrade my DVD player and I've liked what I've read about Pioneer's DV37. What worries me about this player is how compatible/beneficial is a progressive scan DVD player with a HDTV-ready progressive scan TV? Is there signal degradation due to a redundancy in the progressive scan process? Is there signal degradation due to converting from digital to analog in the DVD player, then converting from anolog to digital at the TV's progressive scan processor, then converting back from digital to analog to display the picture? TV's with built-in progressive scan, 3/2 pulldown,line doubling technology offer much improved picture quality of NTSC broadcasts, I'm just wondering if these get in the way of progressive scan DVD players? Any comments or thoughts on this would be appreciated.

I am not familiar with your TV, but I do own a DV-37 and you can switch between progressive scan and interpolated signals. I suspect that when using prog. scan out from the DVD player you can bypass your tv's prog. scan processor. You can then compare the two processors and use the better one. The few times I have read about this I seem to recall that the DVD players prog. scan outs were ususally the winner in a face off. I would check with your Loewe dealer, they should know if the prog. can be switched off on your tv, or if it is automatically bypassed.

Basically the line doubler in your tv is line doubling in tha analog domain. A progressive dvd player does it in the digital domain and is better at the job. 3/2 pulldown reduces the artifacts in film based stuff. A good line doubler will help ntsc stuff as well. Yes all of that digital to analog conversion is bad. The less conversion you have the less of a signal degradation. But with all of this said it still really depends on how good the doubler is in your set. Some are about as good as a progressive scan dvd player, like the Pioneer elites for example. But most are not and the progessive dvd player will be better. Personally, I am going to keep my current dvd player and use my line doubler until the dvd-a, sacd stuff sorts out and maybe I can get a combination player.

Dovetail- I have the DV-37 and the Elite Pro610. The progressive output of the DV-37 is better than using the built-in line doubler of the Elite Pro. Yes, it is closer than with other sets, but the DVD progressive output is preferrable. As for waiting for the format wars to end, DVD-A or SACD, you may be waiting for a quite some time and for minimal improvement in an HT system. Just my .02
