I have a patched both of my dtivos. I have MRV and HMO setup on both. The HDs were upgraded via MFS Tools before I knew about the additional things that I could do with my boxes. I have applied the superpatch67all to open up my functions that I now have. I use DSL and do not have a router as the DSL modem is acting as a router and I have all of my devices plugged into an unmanaged switch. All devices in the home that are on the network are given their IP address from the DSL modem. I don't have a hardware firewall, just zonealarm on my PCs to keep unwanted traffic from going in & out. What I have read is that the TiVo boxes can call home via the internet if not blocked. With this type of setup are my boxes talking to the TiVo servers? I pulled my phone lines after the upgrades to prevent the boxes from phoning home via that method. I have not applied any additional scripts either such as zipper or the enhancement script. I tried to setup my linksys router when I first setup DSL but it did not work. Do I need to try and get a hardware firewall in front of these boxes if they are talking to the servers? Thanks Frickn'
