Can progressive scan dvd player look better in interlaced mode on some HDTV's (CRT)?

[smithman]

My friend who's house i just came from, has a Sony KDP-51ws655 CRT projection tv. He also has a Phillips progressive scan dvd player. I sampled a music dvd that is encoded in tradtional 4:3. He had the tv in one of the stretched modes to fill the screen. My friend and i saw horizontal lines in screen that are only noticed when the dvd player progressive scan is turned on. When the dvd player is set to interlaced, the lines are gone.
The tv has a DCR mode in the video menu, which u can choose interlaced, progressive, cinemotion. If u are watching a dvd with progressive scan on ,or watching something from a source in HD, The DCR mode is greyed out. U then can not select a DCR mode. IF you are watching anything in 480i, then u can choose the DCR mode.
Can it be the fact that the tv displays everything to 1080i, make the picture look worse with dvd in progressive scan mode?
I have the Sony KP-46WS520 with an older dvd player without progressvie scan. I do not see the lines on the same dvd video. I only see some lack of detail of the video since its not a HD source. Can some one please give me more detail on what is going on.
Also, how would these tvs act with a upconverting dvd player. Thank you for any help.

it is very likely that the tvs have better deinterlacing/scaling circuits than the (older?) dvd player.

Since your tv is an analog display (not a dlp or lcd/plasma type) there is going to be a digital to analog conversion somewhere along the line. for this reason, it makes it hard to tell about using an upconvert player. you may or may not see any difference. and it might end up that the tv still has better scaling in it!

if using the HDMI lets you hook up other gear, like an xbox, with component, then that is a compelling reason to switch. otherwise i'd say make sure you can return the upconverting player. or save the money for blu-laser dvd.
