    I have always set the DVD player to progessive scan playback believing that it was the best way to watch DVDs. I had noticed some chromo bug/pixalation on the walls but never really thought anything of it

    A few days ago I was watching JFK and I noticed during one part that the disortion got pretty bad. This is the scene were Costner goes to the restroom in the airport and we get close up of his face which is near the stall wall. The entire red wall was pixelated and distoreted. This got my attention and I now notice it alot in everything I watch. Peoples skin will get distorted during close up etc, walls are blotchy etc..etc..

    So before taking it back to the store I remembered I could switch btwn prog and interlaced...so I did...and low and behold the picture was fine. Very little to no distortion at all.

    So my question is...is there something wrong with the DVD player or are somethings just better to watch without progressive scan. If so, how can I tell so I dont have to stop the movie midway to switch settings.

    Actually, it appears that when you turned off the progressive signal on the DVD player, the TV is not doing the progressive scan processing. How was the player hooked to the TV, component or some other interface?

    component video cables

    I have also noticed that the picture as a whole dims when switched to interlaced making me adjust the settings of either the DVD player or the TV each time...its real hassle !

    I had some service done to my TV a few weeks ago (gun alignment for color banding) and I asked the repair man about this and he said that its all in the DVD player (meaning the cause of my problem) but I am not sure he totally understood what I was talking about.

    Is there a way to check if the TV is not doing its job? or if its the DVD players progressive playback?

    Thanks for the help

    If the picture is geometrically correct, then the TV is properly handling the interlaced versus progressive issue.

    It is not unusual for the picture as a whole to dim when switching the player to interlaced (or progresive) and brighten back up when switching the other way. This is either a shortcoming of the player in not constructing each output exactly to spec or a shortcoming of the TV in not giving consistent results for incoming video signals conforming to spec. You need test equipment to prove where the shortcoming is.
