Sometimes YouTube videos are marked as unavailable due to a country restriction, but it is still possible to view them by using a simple URL trick, which will open the video in full screen and will hide adverts.
The video you want to watch has the URL:
youtube.com/watch?v=ab12C3dE4g (don't try and watch this as it is a made up example.
Remove the 'watch?' and replace the '=' with another / (highlighted in red above).
The URL now looks like this:
youtube.com/v/ab12C3dE4g
That's all there is to it.

I was always making notes on scraps of paper about tips and facts I'd read in books and magazines, seen on the Internet or on TV. So this is my paperless filing system for all those bits of information I want to access easily. (Please note: I live in the UK, so any financial or legal information relates only to the UK.)
