frequency of 711625000 is not a straight US-Cable frequency but one of
the others  IRC or HTC...You might want to try scanning with a different
set of choices on the Scanning Setup page:

Close, I live in Australia, Wollongong to be exact, Frequency looks ok
from http://article.gmane.org/gmane.linux.drivers.dvb/32961 . I've updated
the modulation but I dont think this will change anything, I've turned
further debugging on and have dumped logs from a Working recording and a
Failed recording. I have uploaded these too a webserver
http://seven.dorksville.net/Logs.zip
If someone could have a look at these and offer some suggestions it would
be greatly appreciated.

Thank You,
