The Mac and the PC version of Premiere Elements use exactly the same template format, so the DVD/BluRay templates we offer on Muvipix.com will work for either version.
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/12.0/ONLINE/DVD TEMPLATES/ALL_LANG/[Category].
To add a template to your PC version, place the template files in a new folder (named what you'd like the template to be named) in C:/PROGRAM DATA/ADOBE/PREMIERE ELEMENTS/12.0/ONLINE/DVD TEMPLATES/ALL_LANG/[Category].
AN IMPORTANT NOTE: Make sure that any templates you save to this ONLINE/DVD TEMPLATES area on either a Mac or a PC include, in the folder, a file called DOWNLOADED.TXT. If your template does not, copy it from the folder of another template that you have downloaded! If this file is not in the folder, the program will try to download another file over it and will erase your new template. (Our newer templates have this file included -- but check to make sure!)
When you next start the program, the new template will show up under the selected category of your DVD/BluRay templates!
