Agreed. Maybe we just shouldn't cause an error if the VideoControl
returns EGENERIC but just go on with the video device setup.

Yeah, I have that problem too. I'm not sure if it's due to the drivers
not implementing the API correctly or if I'm doing something wrong. My
code looks like the example they give in the spec so I'm kind of
puzzled. Based on what I undestand, apps should be able to use that kind
of code to build a controls interface (with sliders, buttons and all)
automatically. I'll try to find an app which already does to see if
their code does something differently.
