[linux-dvb] dvb_usb_dib0700 tuning problems?

Hi,

Hoping someone can shed some light on this!

I have an Asus U3000 mini usb dvb-t tuner and I'm struggling to get it
working properly. I have tested the card in windows xp with the same
antenna and it works flawlessly, receiving all channels.

I am using ubuntu hardy heron with the 2.6.24-19-generic kernel which
(should) work out of the box. Device is recognised and the correct
dvb_usb_dib0700 module is loaded, with the correct devices created etc
etc. Correct firmware is in /lib/firmware/2.6.24-19-generic.

Scanning using kaffeine gets me some channels (I'm based in Perth,
Western Australia) - I get SBS & SBS HD but no other channels. 

It appears to me that there is an issue with the tuner changing
frequency (check the output of scan...), I'm new to dvb and a little
stuck, any help would be massively appreciated!!!

Here's some technical output:
