[pbs] Attempting to download a playlist is only giving me one video

[keybounce]

youtube-dl -f 'bestvideo[height<=480][ext=mp4]+bestaudio[ext=m4a]/[height<=?480]' --sub-lang en --write-sub --recode-video mp4 --yes-playlist 'http://video.pbs.org/video/2326108547/?playlist=true&autoplay=true'

Fetches the first video, only.
Does get the subtitles now :-)

[remitamine]

Ha. When I play it, there is also a "next video" in the browser, and I can go "next", "next", "next" and see all of the nova episodes I want to watch.

[remitamine]

this what i get when the video finished.

[keybounce]

Aha!

When I was not logged in, I saw one video.
When I was logged in, I saw a playlist that went to the next video.

That might be a hard one to support :-).

[remitamine]

i don't have an account so i can't work on it.
may be if some has access can help here.
