At one time, we supported upgrades for standalone TiVo Philips and Sony models and we suspended TiVo support to concentrate on ReplayTV. Due to a number of demand for reasonably priced upgrades for TiVos, we will start accepting drive upgrade orders for TiVo owners. To keep things simple, we are limiting our offerings to single drive replacement upgrades.
For Standalone TiVo Series 1 and Series 2: a full line of reasonably priced single drive upgrades with the same commitment to quality and reliability that we give to our ReplayTV line. Why don't we offer upgrades for all TiVo models? We can load any TiVo software on any drive but we only sell drives that we can guarantee with our 100% testing.
