[linux-dvb] DVB scan fails with Nova-TD - please help?

[Stephen G]

Hi I have a Hauppage nova-td USB stick and I'm using Ubuntu Gutsy,
 Kernel  2.6.22-14.  I cannot seem to discover any channels when scanning.
  When I use the nove-td USB stick on a Windows PC (same cable and
 connection to roof antenna), I can pick up and watch about 65 channels!

I downloaded and compiled and installed the latest drivers as per the
 instructions on the wiki.  It seems as though the stick is detected ok:

I set the built-in amplifier on:

sgreszcz at 247:~$ sudo cat /sys/module/dvb_usb_dib0700/parameters/force_lna_activation
1

When I scan however, I get nothing:

sgreszcz at 247:~$ sudo scan -5

I've also tried dvbsnoop:
