I have tried many different DVD decoder/ players to no avail on the secondary display. If you cross the two displays, they all crash. I have had trouble with most non-standard uses of the Secondary display (some applications simply change the secondary to the primary display when you try it. All I was trying to do was make stuff on the Primary display work the same on the secondary. I don't think Windows supports it (it IS much better than. say Windows ME dual display support).
