Ok...I just called TiVo and they said no one else had complained about this problem. After the 9.1 update my S3 TiVo has become basically unresponsive (and it has gotten progressively worse). It locks up. After a reboot it finally comes to menus, and it takes about 15 minutes for anything to come up after each key press. It is completely unmodified (OTA only, no cable cards or even basic cable, and using ethernet) and was working great with the previous software version. (Edit: Now it has started rebooting about 20 min after it freezes) They gave me a case number and told me that if they hear of anyone else with the same problem that they'll have their engineers look into it...but I can call back and check up on the issue if I don't hear back from them. Anyone else experiencing this?
