What does it mean when they say in the manual, that the USB port is for future use. You can see those USB ports on all kinds and all Brands of satellite receivers since years. What are they planning to do with it in the "Future"? It has the same shape like the ones on a PC, so you couldn't hook it up to a PC. So it can't be that. Or is it for example to hook an external HD to it via USB cable? Or is it for a Digital camera? I am not really a computer illiterate, but I just can't imagine what engineers are trying to use it for.
