since your issue was different from the original poster in the thread you originally posted in, I have moved it into your own thread so answers can have direct relevance to your issue.
can you provide more info on your issue?
what is happening to your internet videos?
are you getting an error message?
is it across the board, or only certain videos on certain sites?
no, it's not CC (as certain on that as anyone can be)
because I have had it happen on my PC, and others, as well.
problem is I don't exactly remember the remedy, but I'm sure it would have included trying another browser, and my go-to browser is Firefox, also make sure you get the latest FlashPlayer for it.
and for good measure, update your video card to the latest software version.
if you Google it, it was a fairly common problem, mine would play for about 10 seconds then the video would cut out.
what OS are you on?
I have a sneaky suspicion mine corrected itself when I went up an OS, either to 8.1 or 10.
but I do remember investigating the area that Firefox (and most browsers) are migrating from FlashPlayer to HMTL5, so maybe it's only flash videos you are having issue with.
