The point that Barry needs to realise is that dvb devices do not make
/dev/videoN devices nodes. It makes
/dev/dvb/adaptorN/{demux0,dvr0,frontend0,net0} nodes.

There is a good description of using udev here:

http://www.mythtv.org/wiki/Device_Filenames_and_udev

There is a specific section showing how to set up a dvb device.
