Philips DVP642 DivX-Certified Progressive-Scan DVD Player
has difficulty with dirt and layer changes
you have to be willing to live with skipping video and sound whenever it runs into a layer change or dirt--when it plays well, and it can on about 1/4 of my dvds, it is great but I don't like the poor performance on most dvds--I bought another player and have had no troubles since (using the same dvds that were unplayable on this player)
