[log entries snipped, looking good]

So your driver installation seems to be ok, but ...

Maybe you should take this to the VDR list, as your driver seems to work
but VDR has problems.
I'm not good in reading Oopses, but what buffles me a bit is that the
call trace tells something about the parport_pc module, which has nothing
to do with DVB...
