In linux kernel since version 2.6.29 (release Date: 2009-03-23)  
If you say Y here, the DVB subsystem will use dynamic minor
allocation for any device that uses the DVB major number.
This means that you can have more than 4 of a single type
of device (like demuxes and frontends) per adapter, but udev
will be required to manage the device nodes.

If you are unsure about this, say N here.
