I get the same on my Nova-T DVB-T card here on the outskirts of Melbourne in 
Australia.  I'm using the frequencies given for the Upwey repeater on the DBA 
website (currently just ABC and Channel 9 are broadcasting) and I get:

ABC:

./dvbtune -f 662500 -i
Using DVB card "Grundig 29504-401"
tuning DVB-T (Australia) to 662500000 Hz
polling....

<transponder type="T" freq="662500000">

</transponder>


Channel 9:

./dvbtune -f 641500 -i
Using DVB card "Grundig 29504-401"
tuning DVB-T (Australia) to 641500000 Hz

<transponder type="T" freq="641500000">

</transponder>

The "Australia" bit is from my patch against Dave's CVS (attached).

I also note that now tune.c needs to include <stdint.h> to pick up the 
definition of uint32_t.

Unfortunately I can't double check whether scan produces the same as I can't 
get it to compile (see other message). :-)

cheers!
Chris
