My family comes from the Parchim area. There are several people on the list whose families live or lived nearby. The LDS does have films available. Mitch Blank, a genealogist with a terrific website, has maps of the area:

and usually can be counted on to have some photographs and other info about the home places of his ancestors. His site has quite a bit of information and is a good place for you to start:

Also visit the LDS site, familysearch.org for more information and to search for film numbers for the Parchim area.
