I found a tutorial with people saying it works; here are the instructions I followed.

I opened a shell as root on my system and launched the following:

wget http://linuxtv.org/hg/v4l-dvb/archive/tip.tar.gz
tar zxvf tip.tar.gz
cd v4l... (whatever the newly created directory name is)
make all
sudo make install

Then I edited /etc/modprobe.d/blacklist-custom and added blacklist sn9c102.

After reboot, I launched sudo gstreamer-properties.

However when I type tar zxvf tip.tar.gz it displays:

tar: You may not specify more than one `-Acdtrux' or `--test-label' option
Try `tar --help' or `tar --usage' for more information.

Why? How can I do this?

Thanks in advance.
