Learn what you need to know about CableCARDs and your TiVo HD box.
Use the TiVo Series 3 cable box
Comcast supports the TiVo Series 3 HD cable box. The box will access local and basic cable channels, ATSC digital antenna channels, and analog antenna channels. You will need a CableCARD to access scrambled digital channels.
If you have an HD television, you’ll be able to record in HD and view live or pre-recorded programs in HD. If you don’t have an HD television, your picture will be in standard definition. TiVo Series 3 HD devices use TiVo’s on-screen guide, which differs from the guide we provide.
For more information about TiVo’s guide, consult the owner's manual.
