Modified version I use, multiple cards:

#!/bin/sh
# Create device nodes for the Linux DVB API with DVB_API_VERSION 2.
# The devices created are suitable for most current PC DVB cards,
# i.e. cards having one frontend, one demux and optionally one
# MPEG decoder.
# The script creates devices for four cards by default.

if [ -e /dev/.devfsd ]; then
        echo "It seems you are using devfs. Good!"
        exit 0
fi

# get rid of old DVB API devices; do it twice for good measure...
rm -rf /dev/ost
rm -rf /dev/ost
rm -rf /dev/dvb
rm -rf /dev/dvb
