Ok, now I've tried with another antenna, both with the jumper removed and 
in place. Have also tried different values for the -i option to scan.
Still doesn't work.
It apparently detects that there's _something_ on the frequencies I supply 
because if I use the wrong frequencies or wrong value for the -i option I 
get "tuning failed!!!" instead of "filter timeout".

I bit more info:

Kernel and drivers tested:
Vanilla 2.6.16.29 + drivers shipped with that kernel
Vanilla 2.6.17.14 + drivers from dvb mercery 2006-10-24

Versions of scan tested:
scan from dvb-apps from dvb mercery 2006-10-24
scan from dvb-utils 1.1.0 (debian)
