Thanks Jordan. That means there is at least a chance that they are region free!
Bob, Grant, a friend can probably do the region code transfer for me, but I know for a fact that everyone is asking him for a favor to transfer their VHS tapes to DVD etc., so I rather not bother him with the transfer unless absolutely necessary.
I also remember from years ago that some of the very cheap DVD players were region code free so all DVD's could be played.
