My network with Tivo acts up and does different things anytime I unplug the wired ethernet cord from the back of my series 2. Sometimes it will work great. Sometimes I can transfer from Tivo to PC, but not from PC to Tivo. That's the case right now. In TiVo Desktop, all my shows are showing up and transfer without a hitch. But when I'm in the Now Playing list at the very bottom, it won't show my PC as on the network, therefore I can't download shows from my PC to TiVo anymore. Has anyone else had this problem? What is there to do so this can be fixed? Help is much appreciated! Thanks.
