ive got my starview 4 box and its working perfect apart from i cant connect my hard drive so i can record. i have a 120gb samsung laptop hard drive in a portable caddy. now as the starview box only has 1 usb port i have had to buy a powered usb hub so i can connect the 2 usb cables from the hard drive but i now i just get the message "please reconnect the usb stick" does anyone have any idea what is wrong? thanks
