Why do some episodes say they won't transcribe?

A few episodes have no captions at the source and no audio Podspun can fetch to transcribe. The Dataweaver keeps retrying for about a week after import, then marks them so they stop holding up your channel's progress. The channel's Transcribed stat in Podspun Dataweaver shows the count. Those episodes still appear on your site; they just have no searchable transcript. If captions appear at the source later, a re-sync picks them up.
