Thanks Ian,

Always good to have an upbeat reply!

The bit that concerns me is this (from scan):

tune_to_transponder:1483: ERROR: Setting frontend parameters failed: 
> 22 Invalid argument

Cheers,

Tom

Dear George,

Do not despair (yet)! :-)

I had similar problems with a Gigabyte U7000 -being able to tune all 
channals except Channel Seven (here in Adelaide).

Now, it's not that there's much on 7 that interests me but
nevertheless...

I needed to change the initial tuning details for Adelaide 
(au-Adelaide). In my case just the Channel 7 details were incorrect.

Perhaps you need to find up-to-date information for au-Perth station 
tuning information and update 
/usr/share/doc/dvb-utils/examples/scan/dvb-t/au-Perth -Try google

Just maybe you'll need to re-compile drivers (although maybe not given 
it's working for one channel). I had to on gutsy and heron. These 
instructions (http://waterwave.ch/weblog/detail.php?id=324130) worked 
fine for me.

good luck

bye
