Copy

76PgzzlSKfk_1080p.m3u8
encryption2.key

into the same folder along with ffmpeg (if necessary). Then run ffmpeg command line:

ffmpeg -i "76PgzzlSKfk_1080p.m3u8" -vcodec copy -acodec copy -absf aac_adtstoasc "76PgzzlSKfk_1080p.mp4"

You're a wizard!

Alright so at first I did that and ffmpeg returned this:

ffmpeg -i "76PgzzlSKfk_1080p.m3u8" -vcodec copy -acodec copy -absf aac_adtstoasc "76PgzzlSKfk_1080p.mp4"

If you wish to override this adjust allowed_extensions, you can set it to 'ALL' to allow all

So I allowed extensions using

-allowed_extensions ALL

and then it worked perfectly! Video is playable.

Since there's a few more episodes I need to download. I need to get the encryption key from each video to do that, right? Thanks!

And looking at your custom m3u8 file, it looks like the only change I need to is to change the filename in line 7 in my photo, correct?
