Did you add the creation of the dvd devices in /dev to the 
make_extra_nodes.sh script of udev?

IIRC these are not created by the udev version of Slack 10 by default.

I have this in my make_extra_nodes.sh (in /etc/udev/scripts

mkdir /dev/dvb
chmod 755 /dev/dvb

for i in `seq 0 3`; do
        echo "Creating DVB devices in /dev/dvb/adapter$i"
        mkdir /dev/dvb/adapter$i
        chmod 755 /dev/dvb/adapter$i
        mknod -m 0660 /dev/dvb/adapter$i/video0    c 212   `expr 64 \* 
$i + 0`
        mknod -m 0660 /dev/dvb/adapter$i/audio0    c 212   `expr 64 \* 
$i + 1`
        mknod -m 0660 /dev/dvb/adapter$i/frontend0 c 212   `expr 64 \* 
$i + 3`
        mknod -m 0660 /dev/dvb/adapter$i/demux0    c 212   `expr 64 \*

        mknod -m 0660 /dev/dvb/adapter$i/dvr0      c 212   `expr 64 \*

        mknod -m 0660 /dev/dvb/adapter$i/ca0       c 212   `expr 64 \*

        mknod -m 0660 /dev/dvb/adapter$i/net0      c 212   `expr 64 \*

        mknod -m 0660 /dev/dvb/adapter$i/osd0      c 212   `expr 64 \*

        chown root.video /dev/dvb/adapter$i/*
done

Please not the the "212" may not apply to you. I'm using 2.6.8.1 and 
iirc older versions of the drivers used a different major number (just 
look at what major number your install script generates)

kind regards -ph-
