Hello to averybody,
I had some problems with avermedia 777 TV Tuner and ubuntu 12.04 LTS i solved it. For that reason i give you my solution:
1. Support for the hardware
Create the file saa7134.conf in this route /etc/modprobe.d/ (sudo gedit /etc/modprobe.d/saa7134.conf)
###############
options saa7134 card=85 alsa=1 tuner=62
install saa7134 /sbin/modprobe --ignore-install saa7134; /sbin/modprobe saa7134-dvb ; /sbin/modprobe tuner ; /sbin/modprobe tda9887
###############
2. Install the package "i2c-tools_3.0.3-5build1_i386.deb":

3. Finally, compile v4l from the page:

4. Restart your computer.
5. Install Kaffeine at last.
Put in console "sudo apt-get install kaffeine -y"
Enjoy it your tv card.
Regards.
