This will redirect you to the same page that was used for the 9.1 release, but the language on the page has been updated to cover both 9.1 (still the latest for the S2 & S2DT) and 9.2 (now the latest for the S3 and HD).
For Series 2 TiVo DVRs the latest release features the Rhapsody Music Service and additional power and flexibility to TiVo Wishlist(R) searches.
For TiVo Series3 & TiVo HD DVRs the latest release also enables the use of a TiVo Verified storage device. (COMING SOON)
9.2 also contains bug fixes for issues on the S3 & HD found in 9.1, so if you’ve had problems, or just want to get it sooner, sign up now.
