Yeah, just to add verbose output:

Any progress here?

Well, I took a look into it - the extraction is fairly easy. API endpoints:

Individual presentation:
https://api.parleys.com/api/presentation.json/<presentation_id>

Channel:
https://api.parleys.com/api/presentations.json/<channel_id>

Speaker:
https://api.parleys.com/api/presentations.json/speaker/<speaker_id>

However, most videos are split into parts (for example: https://www.parleys.com/play/5290a8f9e4b054cd7d2ef4c2), so we'll have to wait until #995 is merged and multi-part videos are supported.

Also, I've found that some videos use Youtube, for example:
https://parleys.com/play/530914a6e4b085f68c6b6516/about => http://www.youtube.com/watch?v=04OrkhLpVqA. Not sure if any other services are used like that.
