The best way to transfer shows from a Tivo to a PC is to use Tivo's transfer software called "Tivo Desktop." Tivo Desktop works only when both the Tivo and the PC are connected to the Internet. The software enables the PC to access the recordings on the Tivo. You can then transfer and watch the shows on your PC. Tivo Desktop is free, but there is also a pay version with expanded features called "Tivo Desktop Plus."
Open the Tivo Desktop software by double-clicking on the icon on your desktop or by clicking "Start", then "All Programs." Click "Tivo Desktop", then "Tivo Desktop."
Click on the button at the top of the screen that says "Pick Recordings to Transfer."
Check the box next to the shows you want to transfer in the new window that pops up. If there are copyright restrictions on the show, it will have a red circle slash next to the show name.
Click the "Start Transfer" button in the bottom right corner.
