The Dallas Video Festival is celebrating its twentieth year this week. We’ll spend this hour with a few of the filmmakers. Bill Buchanan will join us to discuss the plight of abandoned animals as detailed in his film “Companions to None.” Mark Birnbaum and Manny Mendoza will drop by to discuss their work-in-progress “Stop the Presses: The American Newspaper in Peril.” Jennifer Horst will join us to describe the only-in-Texas phenomenon that she covers in her piece “Mum-A-Mia,” and Video Festival founder Bart Weiss will stop in to cover other festival highlights. The festival continues through Sunday, August 5th.
