The issue of downloading videos

[min-jung-kim]

Hi, thank you for your valuable work in contributing the dataset and tasks to the community.
But, I'm currently having trouble downloading videos.
Some videos have been deleted from YouTube. (ex. https://www.youtube.com/watch?v=mstoP8Lg-fU, https://www.youtube.com/watch?v=yfzA_oAMdos ... )
Would it be possible to provide videos from alternative ways?
