I was wondering if anybody might be able to help with this. I am using a Mac Book Air, running MacOSX Lion and originally when I restore it to factory setting I can watch videos, say for example from youtube in FULL 1080p HD but over time when I try to view the same videos, the start to become glitchy and jumpy to the point where I just can't watch them.
It there any way to fix this without having to do another full system restore?
Thanks
