This morning, TiVo released a software update to its newest generation of DVRs, giving them the capability to stream movies & TV episodes from Netflix. This includes instant streaming of more than 300 titles in HD resolution.
Three TiVo DVR models offer this new feature: the TiVo Series3, TiVo HD, and TiVo HD XL. Subscriptions to both Netflix and the TiVo service are required for access. There is no additional charge to customers who already subscribe to both services.
The TiVo web site has instructions on how to find and use the new feature on your TiVo.
Other TiVo DVR models, such as the TiVo Series 2 and DVRs sold or leased by satellite or cable TV providers that run TiVo software do not support streaming from Netflix.
