I'm new to the forum but have been a Tivo user for quite a while. I hate the TWC Navigator as much as anyone so that's why I bought a S3. Cable guy is coming this afternoon to do the cable cards but does anyone ever have a seamless transition with this? Has anyone bought a S3 or THD and had the cable guy install the cable cards, activate them, and then have no problems after that? It seems this process would have to work better than reported here to have been successful at all.
