I've had a persistent problem with guide data threatening to run out and I have to reboot every two weeks. I was gone on vacation for three weeks and my TiVo did run out of guide data. I rebooted, the guide data reappears and everything appears fine except the to do list shows "none scheduled" for all my season passes. I've tried rearranging the season passes. I've tried changing the number of episodes to be recorded. Nothing has helped so far. Does anyone out there have anything else I could try?
