I see there is an option to "push" videos to the Tivo. I have already set up the .ini file with my tivo.com username and password. Now I am confused as to how to actually perform a "push." I have a few questions. 1. Does "push" simply mean that the video is downloaded to the Tivo? 2. Is there a streambaby interface on my PC that I am unaware of? 3. Are the videos actually "pulled" from the Tivo?
