Testing youtube-dl to return series, title and filename from the Plus7 web site in Australia. ytdl returned the error msg advising that I should do a bug report. Can't find any other similar bugs and am definitely using youtube-dl 2017.09.11. I am located in Australia and so am not affected by geo-restrictions.

I am receiving the same issue with version 2017.09.15

Plus7 recently changed the layout of their site so this maybe a contributing factor.

Yes, there must have been a recent change @ Plus7.

I do not get the RegexNotFoundError if I force youtube-dl to use the generic extractor. However, every video I've tried gets:

"ERROR: Unsupported URL: https://au.tv.yahoo.com/plus7/800-words/-/watch/29520134/800-words-season-1-episode-1/"
