Well, lucky you. :) From time to time I get to think that I messed up
something when doing upgrades and everything, but this one I didn't
crack.

I did so as it says in your manual and the messages about not finding
dvb_frontend.h and others was there. I switched the lib/modules
directory with the one that I actually build kernel from. I checked for
the files and they were there! Only then I tried copying the files to
the driver folder only to find out that only then the make procedure
sees them. I still can't figure out why make doesn't find those files in
the kernel tree - it must be something dead obvious. :)

khm... If that is so, then I would see the device but mythtv does not
recognize it. Let me check again... Aaaah, the analog device is there
and working under mplayer (under mythtv only darkness is there although
it says it has found channels so I still have to figure out why no
picture in mythtv).

But the true problem is the digital tuner. It's just not there. No
device, mythtv does not see it (before it did), and I tried kaffeine
just to check and it also didn't show up either (it says No DVB-Devices
found). Now, I have one more computer to check. If there's the same
behaviour then it must be a bad karma I guess. ;)

This is the dmesg in mythbuntu after I unplug and replug the device:

It ends here. When I start a media application like kaffeine, no new
messages appear. DVB device apparently does not get registered (no dvb
entry under /dev).

This part is seen.

What is wrong with this? This is what I get when I hit enter after make
command. Do you mean the settings or something else?

I do this in the "driver" folder:
export KREL=`uname -r`
export KDIR=/lib/modules/$KREL/source
make

and the output is what I posted.

Now, if I say locate the first of the missing files I get: 
/share/dmz/software/Linux/kernel/linux-2.6.30/drivers/media/dvb/dvb-core/dvb_frontend.h

so instead of the 

export KDIR=/lib/modules/$KREL/source

folder I give give him the source for building the kernel

export KDIR=/share/dmz/software/Linux/kernel/linux-2.6.30

But it's still the same (no such file...)

It must be a Debian thing I guess.

Additionally this is my config from the most fresh 2.6.30:
CONFIG_DVB_CORE=m
CONFIG_VIDEOBUF_DVB=m
CONFIG_VIDEO_BT848_DVB=y
CONFIG_VIDEO_SAA7134_DVB=m
CONFIG_VIDEO_CX88_DVB=m
CONFIG_VIDEO_PVRUSB2_DVB=y
CONFIG_VIDEO_EM28XX_DVB=m
CONFIG_VIDEO_CX231XX_DVB=m
# CONFIG_DVB_DYNAMIC_MINORS is not set
CONFIG_DVB_CAPTURE_DRIVERS=y

all other DVB devices and frontends are marked as a module

I wish. I probably have it somewhere something but I'm not really in the
mood for a reinstallation. ;)
