In camera_firewire_live.rb you are trying to connect to a corba
name server on a computer called asgurad.local (just uncomment the
line if you want to use the one from the local host).<br>
In both scripts you do not start the cameras and I guess you do not
start the cameras from another script therefore TaskContext.get is
failing.<br>
