If it would speed up the BUQ it could certainly be done behind the
scenes. Even in the digital world there are multi-input cards some
of which allow simultaneous use and some which do not. We haven't
had to deal with that with respect to the DVB drivers, but only
because they don't support the concept yet. My hope is that the
Linux DVB API will eventually catch up with Linux V4L API.
