I have a Toshiba SD-3805 connected via component cables directly to a Mitsubishi WD62725 DLP TV. All DVD's play fine in progressive scan except two Disney DVD's(so far), Lion King and Beauty and the Beast.
The problem is that the pictures flickers(not pixeling). If you setup through the frames one at a time every other frame is different. For discussion sake, the odd frames are sharp and look OK. The even frames look much less sharp and seem to show a color shift.
Some other clues:
-Does not happen with progressive off(interlaced)
-Happens only during the main body of the movie and the actual movie titles but not during the previews, THX, and titles that are not part of the original movie.
-Is not a problem on tons of other movies.
-Talked to Disney technical staff at length they could offer only that it may be an incompatibility issue with that Toshiba DVD player model.
-Contacted Toshiba and they suggested unplugging unit for 5 minutes. Made no improvement.
Need some input from so of you real knowledgeable folks before I run out and buy a new DVD player. Thanks.
