Can any one tell me if a progressive scan dvd play

Don't waste the $$ unless yours isn't working.

I agree. If you did not already have a DVD player, then I would say go for it. I would not considering buying one as an upgrade. As a side note; some modern televisions have their own noise reduction which progressive scan may not integrate with. In those cases the picture gets worse.

yes, you *do* need a tv capable of displaying a native 480p image, which hdtv's are capable of, and none others of which i'm aware.

If you like the dvd player and it has a switchable progressive scan / normal, then buy it.

I have a Sony DVP s9000es progressive scan for my non-hdtv and it's a beautiful picture. Not to mention it plays SACD and CD quite nicely.
