Ok, my kernel versions are 3.4.2 and 3.4.3.

The apps used to tune are

media-tv/w_scan - http://wirbel.htpc-forum.de/w_scan/index2.html
media-tv/linuxtv-dvb-apps (dvbscan) - http://www.linuxtv.org/
media-video/vlc - http://www.videolan.org/vlc/
media-video/kaffeine - http://kaffeine.kde.org/

A six month later i've already created a channels.conf and still working
with vlc.

A question: How to set debug parameter using modprobe?

Something like, "modrobe dib8000 debug=1; modprobe dvb-core debug=1"?


Thanks for now.
