I found a solution to the problem from here
All you have to do is edit (I had a bit different key path on my vista home primium, so I had to create new keys) registry key HKLM\System\CurrentControlSet\Services\USB28xxBGA\Settings\OEM\DVBTorDVBC to value 1 for DVB-C configuration. Restart was needed to activate the new setting.
