Can't make TV tuner work

I have asked this question before when I was using hardy. Now I have Jaunty.

I have a ViXS PureTV-U 48A3 NTSC/ATSC Combo. It works with windows (but I want to get rid of windows)

I have tried MythTV and MeTV
when I run me-tv I get

dumpa@dumpa-desktop:~$ me-tv --verbose

And a sign that there are no available DVB tuner devices.

Anyone has any idea on what to do next?
thanks
