  1. Cannot get my itunes to play movies. It was working perfectly before I downloaded the new mountain lion software. After downloading this version of itunes still no change.
    I can here the movies and they are playing but no picture.
    What’s up here! I am no IT specialist and need things that are extremely userfriendly.

  2. I upgrated from Lion to Mountain Lion and now I cannot play QuickTime videos in the embedded files for my school. I am taking classes and these are required lessons so I need this to work. I tried the fix I read elsewhere to download and install but that didn’t change anything. Any help would be much appreciated.
