Description

7plus video fails to download with error "no video formats found". Episode 1 downloads fine (https://7plus.com.au/police-rescue?episode-id=PORE01-001) but this second episode does not (https://7plus.com.au/police-rescue?episode-id=PORE01-002). Login not required.

I don't understand the closing + DRM label. I've downloaded whole shows from the same site without issue, including another episode from this same season.

https://7plus.com.au/police-rescue?episode-id=PORE01-001 is not DRM protected.
https://7plus.com.au/police-rescue?episode-id=PORE01-002 is DRM protected.
What's not clear?

[Stuntaneous]

Why would that be the case? Comparable shows have no issue, the first episode has no issue, why would there suddenly be DRM on episode 2 of this long forgotten show on lowly 7plus? It seems bizarre.

Ask them why.
