If you’ve got an HD TiVo and you want to get all of the channels from your cable company, you’ll likely want a Switched Digital Video (SDV) Tuning Adapter. These items are just rolling out in from cable companies around the country.
Briefly, the idea is that this enables the TiVo to tell the cable company which video stream to send down to your unit. So more options are available, since not every stream has to be sent at once. The unit plugs into your TiVo’s USB port and then you plug the cable line into it, and the output from it goes to the TiVo. See more info on our earlier blog post about SDV and TiVos.
Now Time Warner seems to have a way to pre-order the unit for any eligible customer. See this page where you can enter you zip code and confirm eligibility, then sign up!
As far as we know, the adapters will be free for eligible customers.
