MythTv supports DVB, and the ~TechniSat ~SkyStar 2 is well supported under [Linux]. There are some tricks to setting this up, but we'll cover them all below. I have installed all the software below on [Ubuntu] Edgy (6.10). It does not cover the basic MythTv installation, which you are assumed to have done already. If not, the [Ubuntu guide|https://help.ubuntu.com/community/MythTV] is very straightforward.
!! Hardware and connectivity
-Get a ~TechniSat ~SkyStar 2 satellite card. These are currently $145 on Trade Me from [an importer|http://www.trademe.co.nz/Members/Listings.aspx?member=1094847], who lives in Te Awamutu, and is a thoroughly nice bloke.

$145 for a USB remote

I installed the card and didn't have to do anything else. Check <tt>lsmod</tt> for <tt>b2c2_flexcop_pci</tt>; if it's not there, modprobe it, and add it to <tt>/etc/modules</tt> so it will load at boot.
-Now, connect it to your Sky dish, or other satellite dish pointed at Optus D1. The device at the end of the arm off the dish, that focusses
the beam, is called an LNB. LNBs can pick up signal both on horizontal and vertical polarisation
, but not both at the same time.

-uses horizontal polarisation (which sends 18V to the LNB)
and Sky Digital uses vertical
polarisation (12V)
. This difference in voltage means that as of May 2007, you cannot use both Freeview and Sky at the same time. Sky are rumoured to be changing to horizontal polarisation; at that point, you will be able to
use a splitter and connect to both the DVB-S card and Sky Digital at the same time. Until then, your only option is to not use the two at the same time, or to install a [dual LNB|http://www.freeviewshop.co.nz/acer-dual-output-ku-band-lnb-p-368.html]. You will need to run a separate cable to the DVB-S card
.

At this point it is assumed you have your DVB-S card connected to the satellite. Now we can test this.
