Chris,

Firstly, on the dhcp reservation thing, tRio now uses the player's MAC addresses instead of their ip addresses and so you can probably do away with the overwriting step. Give it a try and if it works I'll add it to the "what's new" list of sourceforge.

On the ssdp failure problem, please let me know:
1. what broadcast address you specified
2. what your trio and jreceiver ip addresses are
3. what your subnet mask is
A copy of your trio.xml would also be good.

Cheers
Paul
