    I'm stumped. I believe the video and audio streams come in fragments. I don't think they are encrypted (at least not in a way that requires a Content Decryption Module).

    I'd love to have these lectures in 1080p quality and I'm worried they'll be taken down at some point. Can someone please help? There are 7 lectures in all.

    Thanks in advance for any assistance.

  2. Use youtube-dl with the following command lines:

    Oh, at least some of those will result in the same filename so you can't run all of them in one batch file. Either download one at a time and rename, or add an output filename spec to each line. For example:

    Code:
    youtube-dl -o "Cornell Feynman Lectures 0 Bill Gates Intro" https://projecttuva.streaming.mediaservices.windows.net/b8292783-c8ad-476c-8cd0-6f5965866918/Feynman-Main.ism/manifest(format=mpd-time-csf)
    youtube-dl -o "Cornell Feynman Lectures 0 Project Tuva Demo" https://projecttuva.streaming.mediaservices.windows.net/e6ec130a-ac61-4025-8cb7-b53077808aa8/Project_TUVA_Demo_070116.ism/manifest(format=mpd-time-csf)
    youtube-dl -o "Cornell Feynman Lectures 1 Law of Gravitation" https://projecttuva.streaming.mediaservices.windows.net/5c3823db-d97f-4997-8c81-34920fbc2f03/L1_Law_of_Gravitation_23.97_1500kbps.ism/manifest(format=mpd-time-csf)

    youtube-dl -o "Cornell Feynman Lectures 3 The Great Conservation Principles" https://projecttuva.streaming.mediaservices.windows.net/9ca37f48-6b34-4e34-b181-1f71c5625d21/L3_The_Great_Conservation_Principles_960x720_23.97_1500k.ism/manifest(format=mpd-time-csf)

    youtube-dl -o "Cornell Feynman Lectures 7 Seeking New Laws" https://projecttuva.streaming.mediaservices.windows.net/7d586169-9f83-4155-b053-6971464889cf/L7_Seeking_New_Laws_960x720_23.97_1500k.ism/manifest(format=mpd-time-csf)
    I'm downloading them now with that batch file.

    jagabo, thank you so so much. It's working perfectly. I had no idea youtube-dl could handle this sort of thing.
