Back in July, when TiVo quietly pulled their Series 3 DVRs from stores, nobody knew it but it was just to make way for the next step in the line: Enter the TiVo HD XL

While otherwise very similar to its predecessor, the standard TiVo HD, the XL’s most distinguishing feature is its new, and hold on to your breeches here, one Terabyte hard disk! Now, the old HD model was already the largest capacity DVR on the market – with 160 GB – but the HD XL is 6.4 times as much.

There is a 500GB upgrade HDD for the HD but it still won’t reach the same size as the XL and it’ll cost nearly as much: the XL costs around $600 that’s including a $399 lifetime service plan, while the old HD plus the upgrade will set you back about $500.

If you feel that’s unconvincing there are a number of unique features on the TiVo HD, as well as its XL counterpart, which you won’t find for instance on free DVRs that come with your cable subscription: Watching YouTube videos, the ability to rent and buy Amazon Unbox videos, Rhapsody music, online scheduling, copying recordings to PCs or portable devices (dubbed TiVo To Go), access to video and audio podcasts, and more.

The TiVo HD XL also complies with THX quality standards, and supports resolutions of 480i, 480p, 720p, and 1080.

Although it comes with a backlit HDMI cable that allows it to be used with CableCard devices, the HD XL is designed to be usable with analog cables and OTA HD programming, according to TiVo.
