I have a Toshiba SD-430VSC DVD player (is this considered to be good player?) and a big screen 4:3 Projection TV with built in 16:9 enhancement to take advantage of anamorphic DVDs. Now, when I’m watching a DVD and I press the progressive button on the remote, switching from interlaced to progressive, for some DVD's, like Muppets Take Manhattan, Ghostbusters or Pee-Wee's Big Adventure, the image changes in size. In some cases the widescreen and/or anamorphic DVD now fills the whole or most of screen. So, what I want to know is, why when watching certain widescreen DVDs, does pressing the progressive button on the remote change the images size? Also, what is it that makes progressive mode make some areas of a DVD, such as animated menus or some bonus features like interviews and text that flashes across the bottom become almost shaky..fuzzy and blurred but goes away and back to 'normal' when switched back to interlaced? Is this because it’s a different format? And finally, should I always be using Progressive when I watch movies? Because I notice with some, the picture becomes a bit shaky with select DVDs when switched to Progressive. I’d really appreciate any help by anyone, so I’m not as confused where I shouldn’t be.
