DVB-t and analogue pen not recognized

Hi to all,
I'm writing from Italy and I've an Empire pen dual tv
(http://www.empiremedia.it/site/prodotto.asp?idprodotto=231&tit=Pen%20Dual%20TV%20+%20Hypermedia%20Center&lingua=)
I suppose it is a rebranded Kworld 310u (it has the same shape and in the bottom part there is the following code : VS-DVBT 310U). How can I use it?
Under windows I can see both digital and analog tv, but with my kubuntu 7.10 it is not recognized (my kernel version is 2.6.22-15-generic). Can you help me, please?
Thank you,
Xwang

P.S. in case it is not supported can you suggest me a supported usb device which I can use with my 1.4Ghz centrino laptop to see analogue and digital tv?
