Using a movie file converter is very simple now that I understand how the process works. Recently I needed to upgrade my computer and purchased a shiny new mac. Unfortunately when I first got the computer it would not let me play any of the videos I had saved on my non-mac computer. I went online and tried to figure out what the problem was, and learned that I needed to use a file converter for movies. After downloading the correct software converter, I am now able to watch all these great movies on my brand new mac computer!
