Is TiVo compatible with HDTV?
TiVo boxes are designed to support standard definition television broadcasts. They will not support High Definition broadcasts. It is possible to connect your DVR to a High Definition television, and to some High Definition cable boxes or satellite receivers. However, the DVR will only record programs from standard definition channels, and all recordings will be displayed in standard definition. DIRECTV does have a HD DIRECTV DVR with TiVo service available.
