I can't get an answer from Tivo support, so I thought I'd try here. My searches didn't help, so I hope you don't mind a basic question. (I may need to learn more about searching on this forum.) I have one Tivo Series 2 (80 hour)with a lifetime subscription. I'd like to add another box with a larger hard drive. Do I need a second subscription in order to record on both? If anyone has a recommendation for a compatible box with a 160 GB or larger HD I'd appreciate it. I'd like to be able to share the recordings on both uints as well, so now I am up to 3 questions. Thanks for your help.
