Video keeps on stopping after a circle has come in

Hi,
The video keeps stopping because it takes time to buffer (load) and the the sign about which you are talking is Buffering sign. This is due to a slow internet speed
Once it is fully loaded you can watch it in one go. It is normal and happens with almost all of us.
Good Luck and ahve a nice day.
Rating the solution is highly appreciated.

You can either contact your ISP for a faster Internet connection or use some accelerator software.

You can use Leawo Free Video Accelerator - http://www.leawo.com/video-accelerator/
It can accelerate the loading speed of online video and you can view videos on websites smoothly.

It is definitely your internet speed. I used to have the same problem. I suggest calling your internet company to raise your speed.
