Um... Good question.  It likely depends on the distro you've installed
and whether you've compiled your own kernel.  I'll give you a rundown
of how I do it on a Gentoo system (using the gentoo-sources kernel).

cd /usr/src/linux (current kernel source)

Then:

# grep CONFIG_DVB .config

and look for:
CONFIG_DVB=y    -- yours may be 'n'
CONFIG_DVB_CORE=m   --yours may be 'n'

-or-
make xconfig (if you're in X.. if you're on the command line, do a
'make menuconfig')

Somewhere in there, there are some checkboxes for DVB support.

If they're not checked, take a deep breath (and if you're brave) try:

Make sure those are checked (not selected as modules).

Save, and exit.

$ make && make modules modules_install install

That'll build your kernel and modules and install them (it'll run
lilo/grub also).

You'll then have to reboot. (and cross your fingers :))


Depending on your system, you may not have kernel source installed.
You might try either using 'find' or 'locate' and grep for dvb.

Ex.:  locate dvb | grep ko

That'll let you know whether you've got dvb modules available, but it
won't tell you if they're built into the kernel.
