To use this DVB-T USB stick in Ubuntu, you have to install a newer kernel driver.
Follow the instructions from mcentral.de.
Also you might have to install the firmware files according to ubuntuforums.org.
Finally you need to extract the firmware of the
xc3028 tuner using the manual at wiki.ubuntuusers.de.
(You'll need the Windows driver for this as the firmware is extracted from it.)
After that, use the totem-xine package instead of
totem-gstreamer (uninstall the latter one).
But to make things work, you first have to create a channels.conf for xine to find the valid channels (you need the dvb-utils package):
scan -p -x 0 /usr/share/dvb/dvb-t/de-Berlin > ~/.xine/channels.conf
If you want to try the
totem-gstreamer, try this:
scan -p -x 0 /usr/share/dvb/dvb-t/de-Berlin > ~/.gstreamer-0.10/channels.conf
(or you could just copy the file over, if you already created one)
