I agree!
Please make the videos download-able. (unless it's a breach of some copyright law
)
I can't excess it sometimes when I need it!
It's such a great website 
I completely agree that an option to download videos would be great. Just a quick explanation of the reason why there isn't an option to download is as follows:
> Each video has its own view count, and downloading videos would defeat the purpose this view count. We could assume that 1 download = 1 view, but what if someone downloads a video, falls in love with the presenter and plays the vid 24/7

There'd be no way to factor that into the view count.
> The view count is important because when vTextbook has a sponsor, for example Monash University in 2014, proceeds from advertisements are split based on the number of video views (sadly for me Physics is not one of the "popular" subjects

)
> Our video hosting site has the option to play a short advertisement, like YouTube, before each video. That way our sponsors, again like Monash last year, can play a short promotional video before each vTextbook video is played. Downloading just the video would mean you skip watching the ad!
But yeh, simple things like Ad Block and Video Downloader extensions are ways to get around ads and save your bandwidth

And yes, I agree that it's a bit silly that there is no "vTextbook" board to post stuff like this, but it's not for me to decide what deserves a board and what doesn't
