If that's a Philips S1, you should check to see if lifetime was purchased for it on or before January 20, 2000.
If so, you have a one time only free transfer of that lifetime sub to another TiVo, including the newest ones.
You can call TiVo Customer Service or maybe also use the online support chat function. You give them the TiVo Service Number which is on the sticker on the back where the power cord plugs in, but first go to Messages and Settings (or something like that), then to System Information, and make sure the TSN on the screen matches the one on the chassis.
The one on the screen is the one that counts, because that's the one burned into the crypto chip on the motherboard, and that's the one the TiVo reports to the servers when it contacts TiVo, Inc.
It's unlikely, but not impossible, that someone transferred the motherboard to a different chassis.
