Thanks all , The windows 7 pc is definitely a crash, needs rebooting to start up again.
The Ipad, I do not use much for video watching its only I wanted to watch a particular video that had crashed on the pc so I put it up on the Ipad using safari and it crashed there as well.
At the time I got in touch with the guy doing this painting demo using photoshop as the painting medium and he advised using Chrome or updating drivers at utube.
So now when I use the pc to watch utube videos I will use chrome, I cannot recall if chrome has crashed on the ipad, it might have been safari.
(I/E does not allow me to create favourites of utube videos at my favourite bar BTW)
