Paulist Press Selling Insight VHS Videos
Paulist Press (http://www.paulistpress.com), a Catholic publishing company, currently sells 10 VHS tapes with classic Insight episodes. They're not on DVD yet. Most of the tapes have three episodes.
Visit the site and type in "Insight" in the "Book Search" engine, and they will come up.
The series was produced by the Paulist Fathers, so it's only logical that Paulist Press would sell them.
Let's hope they eventually transfer the series DVD and release more episodes.
(I suggest writing and emailing Paulist as well. If they see there's a big demand, then maybe they'll commit to putting the series on DVD.)
