Wednesday's new episode of Elinor Wonder's Why... on now. But careful now, that latest m3u8 in today's episode... is much honestly fresh & spicy hot.https://kids.video.cdn.pbs.org/videos/elinor-wonders-why/93900aaa-8487-4af0-9cd8-084fbe7e0149/2000224372/hd-16x9-mezzanine-1080p/ewhy122-ep-r2-hls-16x9-1080p_009.m3u8
Also before that, I read your honest feedback for most people aren't working for no reason. There are two things from your different end. This m3u8 direct source, are CLEARLY subject to be region-locked in most countries.
Take a different country in France for example... You're attempting to watch PBS Kids on Elinor Wonders Why, off from the Americas... That one is off limits, under the restriction content rights. Neither the website, m3u8 or both. USA is fine, while here in our Philippine relay... it works fine on our end.
Lastly, you may wanna find a better research in FFmpeg CLI in standalone executable thingy or the m3u8x software.
I'm no technology expert in downloading as a Tech Support-style... There are many ways to download, unless for your highest internet speed plan.
So, just a little extensive FYI.
