Hello,

I have the same tuner and this output is what I have, when there is a low 
or none signal. Dvbscan needs a quite good signal to proceed. Try to 
obtain channels.conf on the internet insteed of scanning, then try to zap 
to some channel and see signal level and error rate from tzap application 
while moving antena around.

I have solved this way my problem with one multiplex, which I couldn't 
scan for months. I have found, that placing antena horizontally on one 
place of my window gives me sufficcient signal to receive :-)
