.. It could also be that "DRM M3U8 Downloader" is now required - but not registered

That reminds me now, I had an error maybe.. 2 or so updates ago where it would fail to download the video and would say something about it not being accessible due to copyright protection. I forget the exact words, I wish I'd taken a screenshot, but I'd never gotten that before and it was only during one update. I had switched to the older SF version for a while so I didn't have to deal with that, but in the newer updates I never saw that error again. I wonder if it's still the same issue underneath? Also, I don't know if it matters but at SF startup where it shows you all the licenses, I see DRM M3U8 Downlader with "3 of 3 Videos Left" listed. Would that not allow me to download at least 3 videos off Atresplayer if that module was necessary?
Regarding the extra clips, I am able to download them without issue. It only shows me one orange button and the window appears to me like in your first screenshot. The weird thing is, it only doesn't let me download the latest 3 episodes (I swear it used to be 4 but I just tested and it brings up the download window for the 4th). All the older episodes download just fine. I thought maybe because they are "Preestreno" (early previews for premium subscribers), but it lets me download the 2 older Preestreno episodes so I don't know why it wouldn't with the other 3.
