Please confirm that your Linux DVB setup is working correctly. Have you tried another Linux DVB application? Is this a new thing? What have you tried?

Yes with Kaffeine it works ok.

if I scan using adapter 0 (DVB-S)
it scans, but it cannot find anything because it's DVB-S (where no antenne is...)

TIA

Import: You are trying to import a DVB-T channels.conf but Me TV is selecting your DVB-S device, probably because your DVB-T device is busy.

Scan: I don't think scanning works for DVB-S and I know very little about it.

I had the same problem. It was a hassle finding the right firmware for the Hauppauge HVR-4000 as there's several to choose between. I think I ended up with firmware v1.26.90.0. From linuxtv.org:
http://www.linuxtv.org/wiki/index.php/Hauppauge_WinTV-HVR-4000#Firmware

Code:
wget http://www.wintvcd.co.uk/drivers/88x_2_124_27191_1_WHQL.zip
unzip -jo 88x_2_124_27191_1_WHQL.zip Driver88/hcw88bda.sys
sudo dd if=hcw88bda.sys of=/lib/firmware/dvb-fe-cx24116-1.26.90.0.fw skip=105768 bs=1 count=32674
sudo ln -s /lib/firmware/dvb-fe-cx24116-1.26.90.0.fw /lib/firmware/dvb-fe-cx24116.fw

And then installing the newest v4l driver, as the HVR-4000's driver in the linux kernel up til 2.6.32 is broken when it comes to scanning (I think 2.6.33 got it right but well have to wait till october for Ubuntu to use that one):

Code:
sudo su
apt-get install build-essential
apt-get install mercurial cvs subversion libncurses-dev
cd /usr/local/src
hg clone http://hg.kewl.org/v4l-dvb-20100130/
cd v4l-dvb-20100130
cd linux/include/linux
ln -s /usr/src/linux-headers-`uname -r`/include/linux/compiler.h ./
cd ../../../
make menuconfig

------------------> Multimedia Support -> DVB/ATSC adapters -> disable FireDTV and FloppyDTV. Otherwise the compiling will fail

make
make install
depmod -a
reboot

After that it was finally posible to get me-tv, scan and/or w-scan to scan DVB-T channels.

:-)
Martin Sander-Thomsen

Forgot to mention:
Me-tv 1.1.6, Ubuntu 10.04 alpha3, Linux 2.6.32

Thanks Martin!

Thank you

ERROR: Sorry - i couldn't get any working frequency/transponder
 Nothing to scan!!
--------------------------------------------------------

any hints?

TIA

No, thank you,Michael, for all your hard work :-)

TIA, what happens if you let Me-tv do the scanning? It succeded when I tried the w_scan -X option, so I can't see what should be wrong with your scan.

If I let Me-tv do the scanning:
as I said above:

if I scan with using adapter0/frontend1 (DVB-T)
it scans in 1 second (and find nothing)

if I scan with using adapter0/frontend0 (DVB-S)
it scans long (and find nothing too because no DVB-S is connected)

TIA

PS: interesting is if I go to
(in german)
Me TV Messwerte
Signalstärke 100%
Rauschabstand 50%

which looks ok for me (adapter0/frontend1)

TIA
