[ros-users] Videre STOC Problem

Great suggestion!  I can fire up videre_stereo_cam/launch/videre.launch 
without error (full startup messages listed below).  However (and 
perhaps this is related to the problems with smallv and coriander), I 
can only see the left image.  So running

$ rosrun image_view ime_view image:=stereo/left/image_raw

gives me an image but

$ rosrun image_view ime_view image:=stereo/right/image_raw

gives me a blank window.  I get both left and right images in Windows 
when running smallv.

Running rostopic list gives:

/diagnostics
/rosout
/rosout_agg
/stereo/disparity
/stereo/left/camera_info
/stereo/left/image_color
/stereo/left/image_color/compressed
/stereo/left/image_color/theora
/stereo/left/image_mono
/stereo/left/image_mono/compressed
/stereo/left/image_mono/theora
/stereo/left/image_raw
/stereo/left/image_raw/compressed
/stereo/left/image_raw/theora
/stereo/left/image_rect
/stereo/left/image_rect/compressed
/stereo/left/image_rect/theora
/stereo/left/image_rect_color		
/stereo/left/image_rect_color/compressed
/stereo/left/image_rect_color/theora
/stereo/points
/stereo/points2
/stereo/videre_stereo_cam/parameter_descriptions
/stereo/videre_stereo_cam/parameter_updates

confirming only the left image is being published.

So then I tried videre_non_stoc.launch and this time rostopic list shows:

/diagnostics
/rosout
/rosout_agg
/stereo/left/camera_info
/stereo/left/image_raw
/stereo/left/image_raw/compressed
/stereo/left/image_raw/theora
/stereo/right/camera_info
/stereo/right/image_raw
/stereo/right/image_raw/compressed
/stereo/right/image_raw/theora
/stereo/videre_stereo_cam/parameter_descriptions
/stereo/videre_stereo_cam/parameter_updates

And I get images for both left and right in image_view thought I'm not 
sure they aren't just the same image(?).

P.S. Here are the startup messages when running videre.launch:
