Hi!
You too are from Europe then? I saw a DvD of the original movie not too long ago in a shop over here (Germany), but there is always a good chance of not finding it. I suggest you to check out some of the European ebay pages, where the DvD is offered very frequently e.g:
www.ebay.co.uk (United Kingdom)
www.ebay.de (Germany) There you would have to search for "In einem Land vor unserer Zeit" to get results about the land before time. The German DvD does include the English version of the movie as well.
www.ebay.fr (France)
