Cannot find channles in MeTV

Hi
I am trying to configure MeTV to work with my Phiips DV-B Card (The card shows as a tda10046h in MeTV).

When I launch MeTV I see the scan wizard. From there I select the initial scan option and choose my location (uk-Nottingham) and the program scans for channels. However, after the scan there are no channels available.

I have used the inbuilt meter and have seen that that signal strength is 0% whilst the S/N Ratio is 100% - so this is obviously my problem....

I have run lspci and the output is as follows - I can't see any problems here:

However, I have plugged a TV into the socket (using the same TV lead) and it works OK, meaning that there is a signal getting down the lead. Therefore the issue must be with the card, my build (Karmic) or MeTV. The Card works OK (albeit under Windows) and as far as I know I'm fully patched with my build. Therefore I am assuming that there is a problem with MeTV, which is stopping me from scanning for channels.

Can anyone provide me with any troubleshooting tips to resolve this issue?

Many thanks in advance.
