Have had Tivo HD for 13 months, worked flawlessly until about a week before Christmas 2008 which seems to be somewhere around when version 11 was pushed out by Tivo. Unit now will reboot itself or go to black screen with beeping when at the Cary Grant scene upon boot up. Unit only does this when cablecard is inserted in slot 1 or slot 2. Unit works fine without cablecard but no HD. Cablecard works fine in the TV itself but not in the Tivo unit. Cable company has attempted to change out card but Tivo will not parity check so not able to view numbers for cable company activation. Multiple calls to Tivo on the issue, they now acknowlege possible issue with software upgrade and want $140 to exchange unit and they put blame on cable company for not upgrading card firmware.

Has anyone run into this before and is there a work around solution?
