Virginia,
go to this website http://www.videohelp.com/dvdhacks
and locate your dvd player.
you may be able to set it (Hack) to play all regions.
(the process is to open a secret menu for region code by entering a sequence of commands and numbers using your remote control, then set the region code to play all regions).
NOT all players can be modified, so read the posts carefully for your model.
Many very in-expensive players are available which can be modified.
So far this is not the case with blu-ray, though there are a few in the 300-500 price range.
pm me if you have questions.
Good luck, Thomas.
