yeah, you're reading it wrong.  ;-)

you can mix 4.5 GA, MP*, and FP* releases in a single environment. 
(but 3.4 is not a choice...)  there are two basic rules to keep in 
mind:

(1) the master server CANNOT be running a revision older than any of 
the media servers.  (e.g. 4.5GA master + 4.5FP3 media server = a 
no-no, but the reverse situation is okay)

(2) some features that depend on master-->media interaction might not 
be available/functional in certain mixed configurations.  Example: 
4.5 FP3 includes a new "checkpoint restores" feature - but this 
feature won't be available for a certain restore if that FP3 master 
server is talking to a 4.5 GA media server for that restore.
