My Stream won't stay on my wired and Fios-ed network and falls off after about 15 min of powering up. Anyone else having this problem? I've called Tivo and they also found that the MAC address on the bottom of my stream and on the packaging wasn't matching the MAC address on their servers. They had me assign a static IP address through my router, using the MAC address showing up on their servers in order to increase its reliability. I've tried this for a couple of days but it still seems to be having problems. I'm going to call Tivo back today for an exchange. This is kinda disappointing, but I'm thinking this is the price of early adoption (I was in the initial group of 600 streams released, with the rest of you guys).
