That would be an issue with the application -- not the driver.

This is *not* the first supported hybrid analog / digital device to
appear and be supported under linux.  There are many other devices
that allow analog and digital video reception, while only allowing one
at a time.

The application needs to treat the analog and digital interfaces as
two sides to a single device.
