Have you ever noticed on the time-line bar when watching a movie clip, part of it is a lighter colour than the rest of it, or it freezes for a second.
The lighter part is how much it has actually downloaded.
That's because it has not downloaded quick enough for you to watch it with out it freezing, (it froze basically because you did not yet have that part available on your PC)
OF, No, sorry, I haven't actually, because I don't watch films on here; mainly use the radio facility when I'm 'twiddling' on something.
Kitz, Thanks for that too, I have Antivir Task Manager running and every now and again I click onto that to see what's going on, not that I pretend to understand most of it
but it does indicate that there's a lot going on that I didn't know about
