While its overall visual performance is unlikely to differ from TiVo’s existing HD unit, the new HD XL delivers expansive storage in the form of a sprawling 1TB (terabyte) hard drive capable of storing up to 150 hours of high-definition programming or a mind-blowing 1,360 hours of standard-definition (SD) content. Beyond the advantages of its massive hard drive capacity, the HD XL also supports its “exceptional” video playback by providing the user with cutting-edge sound thanks to the inclusion of full THX certification. It also comes complete with a handy, backlit Series3 remote control and an included HDMI connection cable.

But there's at least one company that isn’t succumbing to all this smaller-is-better madness: TiVo just announced the TiVo HD XL. Stuffed like a Cornish hen with a terabyte hard drive, it’s the highest capacity DVR available, with room for 150 hours of HD content. That’s, like, every Olympic event you actually care about plus all 60 episodes of The Wire. It’s an entire season of Sunday Night Football with more than enough space for your Food Network-obsessed roommate to go balls-out on Batali. But more importantly, it’s enough storage to accommodate the 2009 HDTV mandate, when even your homely local news anchor will be piped into your set in high-def.
