I'm using the latest DVB driver (the youngest file is DVB/driver/stv0299.c
dated Sep 20) and can't say I'm observing this. When I stop VDR I can 
successfully unload the driver.

With VDR running I get:

video:/home/kls/vdr/VDR # lsmod

After stopping VDR it is:

video:/home/kls/vdr/VDR # lsmod

8139too                16128   1  (autoclean)

And finally after unloading the driver:

video:/home/kls/vdr/VDR # lsmod

ipv6                  117744  -1  (autoclean)
