Sorry, I wasn't able to find the "property API" you mention.  I didn't see
anything about a bandwidth property in the VDigProperty.h or IOXVideoParams.h
I downloaded.  I looked on the apple developer site, and found the calls
VDGetDataRate() and VDSetDataRate(), but they don't seem to be implemented.
So I assume the bandwidth property is a selector to your
VDSetVideoParamValue().

As long as I'm asking for selectors, could I have the one that homes the
Orbit QuickCam?
I know it exists, because the home button on your SG control panel works!

Thanks again, and sorry to be a pest.
