Perhaps your answer is correct...if a person is running Windows. I have tried all sorts of fixes with no improvement.
I just ran the same Google News video in Ubuntu and the problem is completely gone. With that in mind, I will ask the same question again. Why do I get audio and video hesitation when I run videos in Windows and how do I fix it? I have tried everything in Adobe and Windows that I can think of.
Thanks to anyone who can help.
