Partially true.  To be able to do Toaster Effects (transitions) you
need 2 synchronized video signals.  If you have just 1 consumer video
player hooked up to a TBC, then you'll only be able to do effects
between that player and one of the toasters built-in signals (like
the still store or a background color.)

Having just one TBC and a consumer player is not useless though,
because one of the neatest things you can do with the Toaster is
use it as a still store (and video image painter.)

If you want to do Toaster transitions between two tape sources or 1 tape
and a camera, you really only need 1 player that has a SYNC IN.  You
would sync this player to the time-base corrected output of the player
without the SYNC IN connector.

If you're going to invest in a Toaster and you only have 2 consumer
video decks, you can still get away with it by using 2 time base
correctors, one of which will take external sync.  (Of course both TBCs
will need to be of the "infinite window" variety. Nearly all are today.)
