Thank you for your replies.
I left it alone, after another hour and a half, I went out
to get a newspaper, when I got back, another hour later,
everything was working!!!!
I sort of suspect a fault in my machine, for a couple of
days now, it seems to be doing a lot of buffering of the
videos, this is usually a very fast machine and I clear the
cache every evening, before I shut down, unless of course
the update has solved the slow-down, I will see and let
you know.
Mike.
