I asked this question in another forum and half of the time they were confirming that whether its Kilobits or KiloBytes so its kilobyes/s and not kilobits/sec.
Yes, my video stops randomly and sometimes a loading circle shows up.
But I don't know why its my computer's fault?
1 megabit = 0.125 megabytes. So your connection may not be really good. I (with about 5Mbits) get buffers with resolutins higher
than 720p most of the time
. May made some confusions in last post.
It would be your computers fault if video would stop without circles circling.
