No Channels on DVB-t

[Laurent]

Hello!
I'd like to use my Free com DVB-t USB-receiver, but encounter an problem I 
could not resolve myself. The stick has art.nr 25452. It is recognized 
correctly (it's shown in lsmod, dmesg). In Kaffeine, the "Digital TV" button 
is hown also, but when I scan for channels, it doesn' find any of them, 
allthough the signal goes up to 100% sometimes...

Can anyone helpme?

Laurent
