The Mac and the PC version of Premiere Elements use exactly the same template format, so any of the DVD/BluRay templates we offer on Muvipix.com will work for either version.
Just unzip the template files and place them in a new folder in the following location. The name you give the folder you create will appear as your template's name.
To add a template to your Mac version, place the template files in a new folder (named what you'd like the template to be named) in MAC HD/LIBRARY/APPLICATION SUPPORT/ADOBE/PREMIERE ELEMENTS/9/CONTENT/DVD TEMPLATES/COMMON/GENERAL.
To add a template to your PC set, place the template files in a new folder (named what you'd like your template to be name) in C:/PROGRAM FILES/ADOBE/PREMIERE ELEMENTS 10.0/DVD TEMPLATES/COMMON/GENERAL.
When you next start the program, the new template will show up under the General category of your DVD/BluRay templates!
