    <para>
      The <application>DVB-Apps</application> package contains a collection of
      command line utilities for controlling and using a digital television
      card/chip installed (possibly through a USB port) on your computer. These
      are useful for scanning to make an index of the available channels, tuning
      the chip to a chosen station or recording the channel to a file on your
      computer so you can watch it at a later date.

    <para>
      There are many TV chips available so it is not possible to give guidance
      on the kernel config for all of them. <command>lspci</command> from
      <xref linkend="pciutils"/> and Goggle are your friends. One possible
      gotcha is that some pci cards (such as the <ulink
      url="http://www.amazon.co.uk/Hauppauge-WinTV-Nova-digital-tuner/dp/B000I1RHWA">
      Hauppauge Nova T 500</ulink>) present themselves to the motherboard as a
      USB controller and the TV chip on the card communicates with the
      motherboard via this USB interface.

        Create a channels.conf file listing the channels available from your
        local transmitter. If it's a terrestrial transmitter there should be a
        file with its details in /usr/share/dvb/dvb-t. If it's a satellite the

      If you give it ten seconds or so to buffer you can then start to watch the
      file with a video player such as <command>xine</command> or
      <command>mplayer</command>. The advantage of watching TV via a file in
      this way is that it allows you to pause playback and rewind if you want,
      plus you can watch the file again later.
