Precise openni kinect rviz

edit

Hi guys, I'm having trouble with viewing images on rviz using the openni_launch stack. I recently updated my machine to Ubuntu 12.04 and to ROS fuerte. After the update I cannot seem to view any images. The openni.launch file has a few major errors along with a lot of exceptions, and I don't understand what it is saying. Here is the output:

[ERROR] [1337870775.117975609]: Tried to advertise a service that is already advertised in this node [/camera/depth_registered/image_rect_raw/compressed/set_parameters]

And then finally, when I try to view an image in rviz following the guide here: link text Rviz says no messages received for the topic in the GUI and in the terminal sometimes it says dropped 100.00% of messages so far sometimes it doesn't.

On maverick and electric I successfully had rgb-d slam up and running.

Finally, I am new to ROS and have finished the main tutorial but am still wondering if there is any other useful guide out there to learn a bit more, especially about what is the best stack for controlling the iRobot create or what is the best place to get started writing ones own packages that interact with other open source packages. It seems very overwhelming when most packages have 1000s of lines of code. I am running on a bilibot by the way which is basically just a poorly documented modified turtlebot with no community.

I am also following this thread link text But our problems seem to be slightly different.
