I have an S2 with lifetime subscription and an S2 with no subscription. Can I use the unsubscribed S2 as a dumb DVR and manually record programs? Can I network it with my subscribed S2 for playback? I'm fearing an unscubscribed TIVO is just a large paper weight. Not happy that TIVO discontinued lifetime subscriptions. The monthly rates are ridiculous. I'd sooner defect to my satellite provider. (Sorry, ranting ) Thanks in advance for any guidance.
