Apparently - as I discovered after my initial post - progressive multi zone NTSC/PAL player is here already (http://www.avsforum.com/ubb/Forum4/HTML/002857.html).
Would the standard US DTV that accepts progressive signal (whether component or RGB) be fine for such a player? What about those...
Has anyone tried this:http://www.tvone.com/CDM-830T.htm
And another question: with the progressive DVD players becoming more common how does one go between PAL and NTSC (tenlab and tvone don't seem to be equipped for handling progressive signals).
