If I change the MAC address of one of the turbonet cards from the default, I understand that this will solve the root problem of clashes, my router will still be assigning DHCP IP addresses though won't it? This can be a bit frustrating and/or risky, first to find a tivo on the network, then it's not immediately clear which tivo you're logging onto. Ideally I think what I need is static IP's for each of the tivos, so that I can set up individual shortcuts to tivoweb into each. My son is a compulsive fiddler, so I don't want him accidently buggering about in 'my' tivo!
