I have not heard of the Bancroft Brothers podcast, but I'll have to check it out.
As far as the craft of animation and comic booking goes, I don't listen to any strictly christian podcasts. These are the ones I listen to:
Chris Oatley's Artcast/Paper Wings Podcast
Animation Addicts Podcast
and Lean into Art
The Christian podcasts I listen to are:
The Reformed Pubcast
The Reformed Kidcast
The Dividing Line
Calvinist Batman and Friends
Jesus Changes Everything
Stand to Reason
And for some non-Calvinist podcasts consider:
Line of Fire w/ Dr. Michael Brown
Bob Enyart Live
Heart of the Matter w/Sean Mccreany (Mostly preaching to Mormons. still good stuff)
Yeah man, Dr. Michael Brown is pretty good too, especially when dealing with the homosexual agenda.
Also, I recently found "The Bancroft Brothers Podcast." It's all about animation, and it's pretty sweet!
