Hmm, works fine for me:

sezier build-2.4 # cd /tmp/
sezier tmp # cvs -dhunold@linuxtv.org:/cvs/linuxtv co dvb-kernel
sezier tmp # cd dvb-kernel/
sezier tmp # cd build-2.4/
sezier tmp # ./getlinks && make install
sezier tmp # ./insmod.sh load

Loads and runs flawlessly.

Have a look at /proc/ksyms. If the "videobuf.o" module is loaded, the 
exported symbols must be listed there. If they are, but with some kind 
of prefix or postfix, then there is something wrong with the way the 
modules have been build.

A good candidate is "Set version informations on all modules" in the 
kernel configuration dialogue. If this is set and you save the 
configuration, all functions from modules build afterwards will get 
prefixes to identify these modules in a unique way.

If this is set, try to unset it, recompile and install the kernel again, 
then recompile the dvb driver and load again.

CU
Michael.
