I've got a Kworld dvb 250u usb card for watching freeview digital tv on my pc.I had it working but done a fresh install of windows xp pro service pack2.Now i can't get it working again.I've installed the software and when i try watching tv it come up with this error message "Cannot init Direct show interface" . Does anyone have ANY ideas on how to resolve this.I would appreciate any responses which would help me as i've been pulling my hair out over this and haven't got much left as it is anyway
