Alister Kunga,
Try this (comment 1 line):

You'll still get the error but should continue with tuning.

Also, if your kernel is compiled with dynamic debug try this:

echo "func dtv_property_process_set +p" > /sys/kernel/debug/dynamic_debug/control
echo "func dvb_frontend_handle_ioctl +p" > /sys/kernel/debug/dynamic_debug/control

Then tune a channel and paste the kernel log here.
(use something like: "dmesg | grep DTV_CLEAR -A10 -B10").

nothing happens

echo "func dtv_property_process_set +p" > /sys/kernel/debug/dynamic_debug/control

echo "func dvb_frontend_handle_ioctl +p" > /sys/kernel/debug/dynamic_debug/control

Does dmesg have any reference to dvb_frontend.c ?

Also, did you try the hack? (comment 1 line)

I suspect that the installed dvb drivers are not DVBv5.

Did you include these chars on the command?? ............... ^^ ").

Yes i have

That's some other issue, I'll update the driver package within the next hour.
Another customer has told us about this issue today and I just had a look at it.
This issue can be closed and marked as resolved.

You shouldn't... the command is just:
dmesg | grep DTV_CLEAR -A10 -B10

Nice to know. By the way, are the drivers closed source?

We have contracts with several suppliers (which make our life easier).

Drivers are updated.

Can you confirm that the latest driver solves your problem?

(please not the driver got updated just now... you might have to do it again the announcement was too early).

Can you post a link to the drivers here?
It will be useful to save for future reference.

This will install the latest drivers within a few seconds:

cd /tmp
wget http://sundtek.de/media/sundtek_netinst.sh
chmod 777 sundtek_netinst.sh
./sundtek_netinst.sh
