We've talked about Netflix in the past "Netflix Partners With Microsoft. Blockbuster this should have been you!". This announcement just continues that theme.
"Netflix streaming will be coming to TiVo DVRs by the end of 2008.
The ability to stream Netflix movies and TV shows will begin beta testing for select TiVo owners immediately, with an official roll-out scheduled for early December. It will be available on TiVo HD, HD XL, and Series3 DVRs (not Series2 or DirecTV models)."
