When Im on the internet (including Apples own webpage) every time I come to play a video (persumably quicktime on 
's page) It plays the audio but I get no video on screen. Ive tried updating but as my macbook is only a week or two old is this really the problem? It says there are no updates available!
Anyone shed any light?
