Hi
Our computer is new (3 months) and in the last few days it has stopped being able to play video properly. I am not an overly technical person, so this explanation is in "luddite".
we can access the youtube site and when you choose a video to watch, all we get is a green screen and clear audio (mainly for the ads) and then jumpy pictures (more like stills) and garbled sound.
I tried video i have in iTunes and it is a black screen but clear sound.
I am not running firefox on the system and have not upgraded to 8.1 yet.
Any help would be appreciated
