HDHomeRun requires a 100 Megabit connection to record 2 shows at  
once. In fact, it doesn't have gigabit on it, so any extra bandwidth  
would not help unless you're worried about adding to the traffic  
already on your network. If you're that concerned, you can get a  
100MBit card and plug the HDHR directly into the box that is storing  
your recordings.
