Who may I share the videos and PDFs with?

We feel that the following guidelines are fair for both you our customer, and for us:

  • You may freely give copies of the files you’ve purchased to your kids, grandkids, nieces and nephews.
  • If you’re a teacher or tutor you may play the videos to your students in the classroom, but we ask that your students’ parents purchase their own copy for home use.

How do I extract the downloaded zip files?

In Windows:

  1. Right-click a compressed (zipped) file.
  2. Select Extract All from the context menu.
  3. By default, the compressed files will extract in the same location as the zipped folder, but you can click the Browse button to select an alternative location.
  4. Click Extract.

In macOS:

  1. Double-click a compressed (zipped) file.
  2. The files will decompress into a folder with the same name and location as the zip file.

Which media player do you recommend?
