I want to try the wireless card again with cross connect cable to see if the hub is causing the bottleneck.

Well worth trying... these wireless cards often fall back to 2 or even 1Mbit/sec if they can't connect at the ideal 11Mbits/sec.

500Kbytes/sec is a very good result over Ethernet with the currently-released software. The raw bandwidth we get off our dual-P3 server over switched Ethernet into the player and into a disc file is only about 850Kbytes/sec, and there's a fair amount of overhead in the current protocol.
