MacbookPro 2.66Ghz - 8gb ram - OS X 10.7.2
What could cause this?
In playback, the video playback stops ( freezes ) every 5 seconds ( approx ) for a fraction of a second ( about half a second ). The sound carries on as normal - and when the video restarts it has caught up with the sound ( in sync ).
Any idea and how to fix this?
PS - Just checked - and it seems to be in any movie clip on a webpage.
cheers
