Sounds like there is something seriously wrong with your network setup if it is taking 5 hrs for a 30 minute show. My transfer times are better than real time, and that's wireless from the Tivo to the PC.
Maybe you can provide your Tivo Model, network adaptor model, and how your home network is setup in general.
