I have a client who suddenly cannot play avi video files on an imac running 10.7.5 osx.
i am not a huge whizz on iMac so i was not able to see what the software was not encoding the video properly.
When they try to play the video it comes up with moving colour blocks on the screen, but no clear or even fuzzy picture. you can also hear sounds but not anything legible.
is this something to do with codecs?
Can someone help me to solve this one at all.
