I've just got my 42PFL3007T, and upgraded it to the latest firmware. I'm a bit surprised by how long it takes to change inputs. From I select a source and to a picture shows up, it takes six seconds. Is the TV seriously that slow?

Also, what is the network port for on this TV? I connected it, and it recieves an IP via DHCP, but there's no "browse network" source, nor does the TV show up as a DLNA target.
