Thanks to all who have replied.

I have not been twiddling my thumbs in the meantime...

I applied every option recommended and the 1.10 firmware...  No luck.

So I tested under windows.  Still no luck.  Again the card drivers load and
it seems to be working but scanning for channels fails.

UHF reception is otherwise quite good.  Typically at least 80% on live tv
for the weakest (Kordia) multiplex on the HVR 1200 which works perfectly
from the same aerial connection.  I did start experimenting with some
unamplified rabbit ears as an alternative to my external aerial with no
better luck.  I have a usb volar hd which works mostly fine when connected
to the external aerial and when I connect via it's small portable rabbits
ear aerial.  I am in line of sight of Mt Cargill, so I would expect the
signal to be OK.

Maybe I might build an i386 machine and test it in that, we'll see how
conscientious I feel.  I would be interested in the setups of people who
actually have one of these working.

BTW Douglas, isn't the usb disconnect issue fixed by 'options usbcore
autosuspend=-1' and then rebuilding your initrd as described in the link I
included earlier?

I am not interested in the IR setup as I don't have the dongle or a remote
control for the card.
