I've been a 7+ year Tivo user. I bought the lifetime Tivo subscription from Tivo in 2000 and used it on my DSR6001 receiver. Then a couple years later the lifetime subscription was transferred to DirecTV. I now want to dump DTV in favor of a series 3 unit and cable cards but I'm thinking I will get screwed on the whole lifetime subscription deal. Has anyone gone through this scenario before?
