Copy media player from one Magento installation to another

I need to copy a Media Player extension from one Magento installation to another. Extension should be transfered with full back- and front end functionality. Source: I have the full source code for the source installation (all files). Target: Magento 1.7. I have root access, full ftp and admin access. Functionality: Using JPlayer ([login to view URL]) to play media files on product detail view as well as on product list view. Backend upload media files on product. You will transfer the extension to a dev installation first for review. Then make an installation package that will install on the production server.
