This howto is for installing Hauppuage WinTV HVR 1100 under Ubuntu "might work for other wintv cards" no guarantee though...

I used this froum its in french though --> http://forum.ubuntu-fr.org/viewtopic.php?id=73834&p=1

Here we go first check if your card got detected

lspci

    you should get something like:

    0000:00:12.0 Multimedia controller:Philips Semiconductors SAA7133 Video Broadcast Decoder (rev d1) Subsystem: Hauppauge computer works Inc.: Unknown device 6701 Flags: bus master, medium devsel, latency 32, IRQ 12 Memory at eb101000 (32-bit, non-prefetchable) [size=2K] Capabilities: [40] Power Management version 2

      first make sure you have the packacges required for the configuration of the card, open a console and type:

      sudo apt-get install build-essential mercurial linux-headers-`uname -r` dvb-utils

        then get the v4l-dvb files:

        cd /opt/ hg clonehttp://linuxtv.org/hg/v4l-dvb cd v4l-dvb

        make sudo make install

        sudo -s

          then modprobe:

          sudo modprobe -r saa7134-alsa saa7134-dvb saa7134 && sudo modprobe saa7134 card=101 && sudo modprobe saa7134-dvb echo "saa7134-dvb" >> /etc/modules

            now get the firmware compatible with your card from http://thadathil.net:8000/dvb/ then "sudo" copy it to /lib/firmware

            sudo reboot

              I think that was it use scantv or mythtv to scan for channels i will write a tutorial as soon as i get to it
