I have a feeling this is from a reformed baptist organization.
Why because of the apparent support of the 'Radicals' or Anabaptists.
This 3 hour DVD summarized the reformation history using 7 bio movies.
1. John Wycliffe
2. John Hus
3. Martin Luther
4. Ulrich Zwingli & John Calvin (none English, possibly German)
5. The Anabaptists (From the film "The Radicals")
6. William Tyndale
