Hello, this has been bugging me for a few days. I am attempting to run roslaunch openni_launch openni.launch depth_registration:=true on my turtlebot (which is on hydro). It produces depth images fine with depthregistration:=false, but as soon as you relaunch it with this argument set to true, or reconfigure it through `rosrun rqtreconfigure rqtreconfigure, the values fromrostopic echo camera/depthregistered/image_raw` all turn to 0.

Here's what I see when launching openni_launch on the turtlebot:

turtlebot@blood:~$ roslaunch openni_launch openni.launch depth_registration:=true

The odd part is that I have another kinect that I can run into my computer and, running roscore locally, can produce correct depthregistered images. However, if I plug that kinect into my turtlebot laptop, the image is incorrect again. I tried this in reverse too; I plugged in the turtlebot's kinect into my computer, ran opennilaunch, and the image was produced correctly. Because of this I ran sudo apt-get update and sudo apt-get dist-upgrade on the turtlebot, which didn't solve the issue.

Let me know if I can provide any more info, or if someone has had this problem. Thanks
