Hmmm, I've never seen that. I wonder if it's a version thing, as my unit 
is now several years old...

In any event, I added pan/tilt to camstream 0.26.3.  I use the 
VIDIOCPWCMPTRESET in a "reset-to-(0,0)" function to ensure the position 
in case of manual adjust while powered off.  Just used this control 
about 30 times with consistent results.
