For the first time since the debut of TiVo in 1999, TiVo has undergone a facelift. The redesigned interface--available in the new TiVo Series 4 hardware shown here--takes advantage of the hardware's dual-core 400-MHz Broadcom processor and increased system memory (now 500MB). Series 4 units output at up to 1080p, a resolution upgrade from Series 3' s 1080i limit. The high-definition units, priced at $299 for the 320GB TiVo Premiere and $499 for the 1TB TiVo XL (1TB of storage can accommodate 150 hours of high-def video)--mark a long-overdue leap forward for TiVo. Let's see what the new series looks like.
