Is this a "real" usage scenario?  It feels that this is not what most
users will do and it certainly is not relevant for our application.  

Is it possible that if you are interested in such a scenario that you do
the testing?  We have spent quite a lot of time to fix the driver for
real (well full frame) capturing already and I am relucatant to spend
more time for corner cases.  Maybe we should document this as "known
limitations" of the setup?  What do you think?  I'll much rather have a
driver working for real world scenarios than for marginal test cases.

Thanks
  Detlev
