Advertisements So I went to name my tivo hd today an noticed a fourth tivo on my account, it's id started with same 10 digits of my current tivo hd. It shows that it was activated on Aug 1st. Im going to call tivo about this in the morning. The part that annoys and scares me is that my credit card was billed on the 1st for service as well. Has anyone else had this happen? I only own 3 tivos!
