Yep, not a Membership. TiVo isn't a club (technically), but a service.
You don't have a cable or phone membership do you? (You might if you belong to a co-op though).
VIP was the name of the promotion when the Series 3 launched, where for $199 you could transfer a Product Lifetime (its official name) from another TiVo (the terms were pretty broad on that one) to your Series 3, and get a free year monthly service on your old one. There is a similar offer currently in effect for the TiVoHD, where you can transfer Product Lifetime to a TiVo HD for $199, but provided the Product Lifetime is from a standalone, and activated before October 2003.
