kinect: nonsense point clouds for 30 seconds after subscribing

I launch the kinect driver and processing nodes with openni_launch/launch/openni.launch. I have the latest versions of the ROS-openni packages in Electric. I get xyzrgb point clouds, but the depth data is nonsense for 30 seconds after subscribing. Here's a video, where I'm viewing the point cloud in rviz on a remote computer: http://surgical1.cs.berkeley.edu/troubleshooting/rviz_kinect.ogv. This isn't a network issue--I have the exact same problem when I record data on the local computer that the kinect is connected to--c1 on the pr2.

Your link is broken.

Two things to try: plugging the Kinect into a different computer, and a different Kinect. Maybe you've got a bad part...

I forgot to update this post until I noticed that there was a reply. As Mac correctly inferred, this was hardware problem with the kinect itself. Apparently the electronics or wiring was damaged when we prepared the kinect to be mounted.
