I just committed a fix for this defect to the camera_drivers trunk.

As Blaise suggested, I added a new reset_on_open parameter (default
true). You should set that parameter false for the Videre
STH-DCSG-VARX-C.

There are many ways to do that, including setting it on the command
line like this:

 $ rosrun camera1394 camera1394_node _reset_on_open:=false

Before we release that in a C-turtle update, I would like you to
verify that this change does indeed fix the problem with your device.

If anyone else cares to try it with their device, that would also be
useful. My test cameras work fine with reset_on_open set either true
or false. Let me know what camera you tried, how you set the new
option, and what the results were.

Thanks,
