The only thing that you'll have to do that involves mucking around with hardware is to temporarily place your Tivo's hard drive inside your computer. If you've ever replaced a hard drive, then you've already mastered all the technical skills necessary, i.e. you know how to use a screwdriver.

Take a look at this website:

www.weakknees.com

They have very complete instructions re: replacing Tivo hard drives.

Also, this forum will have links to step-by-step Tivo hacking instructions. Incidently, this kind of hacking is completely legal. They only thing you're violating is your Tivo warranty.
