You should be able to see dvb nodes in your /dev even if the module
isn't loaded. If you don't see them use

for most distro's :
# cd /dev
# ./MAKDEV dvb

This wil create an /dev/dvb directory with nodes inside for you.

If you don't have the /dev/MAKDEV either consult your distro how to do
this, or do it by hand:

# cd /dev
# mkdir -m 755 -p dvb/adapter0
# cd dvb/adapter0
The use mknod to make device nodes like this:

# mknod audio0 212 1

This is a list of the nodes:
crw-rw----  1 root video 212, 1 Jul 24 14:14 audio0
crw-rw----  1 root video 212, 6 Jul 24 14:14 ca0
crw-rw----  1 root video 212, 4 Jul 24 14:14 demux0
crw-rw----  1 root video 212, 5 Jul 24 14:14 dvr0
crw-rw----  1 root video 212, 3 Jul 24 14:14 frontend0
crw-rw----  1 root video 212, 7 Jul 24 14:14 net0
crw-rw----  1 root video 212, 8 Jul 24 14:14 osd0
crw-rw----  1 root video 212, 0 Jul 24 14:14 video0


> For mplayer, you need to copy channels.conf from your ~/.szap dir to
your ~/.mplayer dir.
