Power point is not so much the issue here but can mean it's a public presentation. The owner of the work should be asked for permission and how to download the content.
So far all those that I asked have said yes and helped me out.
There it is. Will you ask the content/video owner?
I am trying to download a video from the web so I can incorporate it into a PowerPoint. I will not have internet access at my presentation and it is not a you-tube video. Is this possible?
