Mark,
Dont bother with the lead, TUTV boxes encrypt the data stored on them, you wont be able to transfer it to another machine without breaking the encryption, something that has so far eluded most of us. Also its formatted as a Linux drive so without messing around with extra software you wont be able to read it in windows anyway.
The USB port on the front is not connected to anything but power at the moment although potentially there is the possibility of connecting another hard drive to the machin via this but I wouldnt hold your breath.
Regards,
Graeme.
