A rep for DirecTV tells Consumerist:
A small number of customers who have our older TIVO Standard Definition boxes are indeed experiencing issues with frequent rebooting which involves the software, not the box itself. We are working diligently with TiVo and expect the issue to be resolved today. We know this has been inconvenient and very frustrating and will credit affected customers as soon as possible.
UPDATE: The rep has clarified that the credits will be proactively applied to affected customers’ accounts.
