Here’s what Boris Support has to say:
Hi Chris,
The version of RED 5 that comes with Media100 Suite is only for use with
Media100.
It gets installed with the Media100 Suite install bundle and uses the
Media100 unlock code for registration.
The retail version of Boris RED 5 contains all of the Mac based host
installers.
Purchasing the retail version of RED allows you to install RED 5 into all
supported hosts on your Mac.
I think I might be MORE interested in Red. I could use the same plug-in set across all three of my existing editors.
