Oooh, Now there is some output I Haven't seen in a while (all that
dmesg crap).  It gives me the shakes just thinking about it.

First, we upgraded so that we use udev instead of the that other
'static' thing that FC2 seemed to be using.  (Don't ask, I don't know
:P).

Next, I downloaded Chris Pascoes drivers from the UQ website (ping me
if you can't find it).  I built them, ran that start script, I think I
created links from the udev stuff to the /dev/dvb/blah0 folders.  I am
pretty sure it was then all ready to go with TZAP.

Nope, its just that the channels in AU are so crap they can't stick to
there times and I have to record an extra 20 minutes of every show. 
Then, when I tape two concurrent shows (like NCIS on Sundays) I a
pretty much goosed to record anything else.

Anyways, I hope you get it sorted.  Give me a shout if there is
anything more I can do,
