Am a beginner but have been able to download PBS NOVA and other videos using youtube-dl-gui-0.4 port (need port because can not install apps on the Win7 PC that use to dl videos).

Am unable to dl "Apollo's Daring Mission" and do not know if it is me or the app that is causing this problem.

If can not dl,hope someone else is interested in this video and will make available for dl somewhere.
