Ron,

On the ip address issue, you need to add a reservation for each receiver to your DHCP server so that they get the same addresses each time. If your dhcp server doesn't do reservations (many router-based servers don't), I have built something into the latest alpha which works off the hardware address (mac address), but this hasn't been tested properly. If you want to be the guinea pig, then PM me with your email address.

On the router/dsl traffic, try changing the "send-method" setting in trio.xml from "multicast" to "broadcast" (don't forget to shut down trio first).

Cheers
Paul
