First, the "backup DVD" is just that.
The only reason to use it is if you want every filter available at the time your DVD was created installed in your system.
I have it for two reasosn only. First, if the FilterForge server gets nuked, my Drive get nuked and my Time machine drive get nuke. Second, to show the accountant that I have bought a physical "DVD", as sometimes Swedish Tax ministry has hard times to understand concept of download purchases of software, they are so 1980:ish in their thinking.
The instructions will work, but they will replace the whole FF settings directory, where you own and your downloaded files are.
What I wrote above still stands "
I suggest you browse on the webserver, and have the DVD as backup incase you HD dies...". As the DVD is only as up to date as it was when it was manufactured, and the library is a living organism, powered by the many filter weavers, who make new and updated filters.
