How can it deliver true HD TV via a network when HD TV signals need 1600Mbps transfer rate.

Yes. Just plug a multi-port switch (make SURE you get a switch, NOT a hub) into one of the 4 ports on the router, and you'll have that many more ports. I do this now, I have a switch to which my Roku, PS/2, etc. in my media romm are all connected and 1 cable goes to the router. Unless you go hog wild and buy an expensive managed switch, no impact to the IP addressing, your network will still just big a (now bigger) flat network.

This results in a bitrate of around 19.2 Mbit/sec for broadcast HDTV, slightly more or less for other HD sources like cable or satellite. This is easily handled by 100 Mbit/sec ethernet.
These ultra-high bandwidth speeds (1.4 Gbit/sec or more) we're talking about are only used for transmitting raw, uncompressed digital HD video over short distances - between a decoder device and a digital display, usually via DVI or HDMI cables. That high bandwidth requirement is one reason why DVI/HDMI cables are expensive and limited in length.

Probably not an issue most of the time, but if you were trying to stream HD to two or more devices off of the same switch it could potentially cause a problem, unless my understanding is incomplete (a distinct possibility, I must admit).
