There’s not a ton of info available, except that Amazon lists these product features:
- Does not support recording from two digital cable or satellite channels at once
- Record shows from two basic cable channels, or one basic cable and one digital cable channel, at once.
- Up to 180 hours recording capacity
- Includes Ethernet and USB ports, so connecting to your home network is a snap
- Only TiVo offers exclusive features like WishList searches, Season Pass recordings, TiVoToGo transfers, plus new online services like music, photos, and more!
On the other hand, if you’re willing to wait longer and want to spend a bit more money, you might want to wait for the Series 3.
