@ OP
FYI Input 1 on toaster can take a digital signal WITHOUT TBC for instance DVR/Cable box digital comp out, Digitial mini dv cam, Xbox, DVD player etc etc...
THEN on Input 2 you would route your second source like a vcr or something through the tbc first then into input2
This will give you an A/B situation where you can use the Switcher on the Toaster to switch between input 1 and input2 with transitions or whatever.
