Hello,

I just purchased a Hauppauge Nova DVB-T USB stick and the kernel module and firmware recognizes it well. I have first used Kaffeine to search for channels, but it has found none.

To be sure I even bought a better, an active dvb-t antenna with a 20dB amplifier. And now I used dvbscan to scan for channels, I invoked it like this:

dvbscan -out channels /usr/share/dvb/dvb-t/de-Mannheim

Is this the better way? It takes now longer than 15 minutes, is this normal? Is dvbscan more reliable than kaffeine for searching for channels? If I still find no channels, what could be the cause? In my region dvb-t signals are said to be not too well.

thanx
Malte

Thanks for the hint. But...:

dvbscan /usr/share/dvb/dvb-t/de-Mannheim

"Unable to query frontend status"

Why is it unable to open the device? /dev/dvb/* exists, firmware and modules loaded correctly...

dvbscan is from dvb-1.1.0_CVS20080331

Err, that looks wrong. We haven't used CVS for quite some time (not sure about the date, but pretty sure it was well before Mar 2008, so I'm unclear about the copy you have).

In any regard, grab a fresh copy from here: http://www.linuxtv.org/repo/
(you can obtain it via either a tarball or using Mercurial). Build instructions are also listed on that page (essentially make, make install).

Will this resolve your "Unable to query frontend status" problem? I don't know, but this will be a good starting point. Failing that, lets see the relevant output from dmesg.
