It might seem daunting at first but is pretty easy
Break it down into Steps
1) How do i get a signal into the TIVO i.e. Aerial, Cable, Satellite etc
2) How do i get guide data into it i.e. Serial, ethernet, cable modem, ADSL etc etc
From here we can then start to help you out with pointers to info etc.

OK - the PC side is not that hard
First,
What OS do you have on the PC - presumably XP if you are a newbie
How do you connect to the Internet from your PC
What TIVO did you buy and what parts did you get for it
What is the config of your PC - more specifically do you have a CD burner ??
