Can I receive French terrestrial channels (TNT) in Britain using my Bravia's integrated tuner?

[Marionlam]

Hi,

I have a Sony Bravia KDL-40EX723 with an integrated Freeview tuner (and there is a label at the back that reads 'decodeur TNT integré'), and I'd like to use it to receive French channels without losing the English ones.

Is there a way to use the same TV / tuner / satellite dish for both? How?

Thanks!
