perhaps cx88-blackbird is disabled in your configuration.  No matter -- you
don't need it.

You only have one dvb adapter showing up because the cx88-dvb module does not
load automatically in the version of the repository that you are using.  To
resolve this, add "cx88-dvb" to your init scripts.  This is distro-dependent.
In most cases, you can simply add "modprobe cx88-dvb" to /etc/rc.modules ...
but, again, each distro has its own method.

Please keep in mind that Chris Pascoe's "new" test branch was "new" many months
ago.  His repository is dated as two months ago, because at that point he
updated the repository with the changesets from the master branch.

We were looking for feedback as to whether or not his rounding fixes for the
dvb-pll module did the trick for tuning in Australia -- Thank you for this feedback.
