Hi Rosen,

I am trying to get my Videre up and running and thus reproducing your problem.
Which package are u using to get the initial data stream from the camera:
cameradc1394 from cmu repo
camera1394 from ros-pkg-trunk/stacks/camera_drivers_experimental?

If the former, in how is it different from the latter?

cheers, D.
