I tried that and the output from tzap for any frequency seems to be:

using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
tuning to 722000000 Hz
status 01 | signal ffff | snr ffff | ber 00000000 | unc 00000000 |
status 01 | signal ffff | snr ffff | ber 00000000 | unc 00000000 |


I also tried using dvbtune which gave the following:

Using DVB card "Alps TDMB7"
tuning DVB-T (in United Kingdom) to 490000000 Hz
polling....
Getting frontend event
FE_STATUS: FE_HAS_SIGNAL
polling....
Getting frontend event
FE_STATUS: FE_HAS_SIGNAL FE_TIMEDOUT
Not able to lock to the signal on the given frequency


I know there should be a signal as I haven't moved the aerial and it 
works fine under windows.  I'd really like to get this working as I'm 
fed up with the shoddy windows software from Hauppage.

All help is much appreciated.

Thanks,

Simon
