VCR in the HDTV era

Can either the auto clock or auto channel set functions of a VCR work in the HDTV era? I'm wondering if cable has any sort of backdrop signal that that VCR can use.

Most domestic VCRs are equipped with a television broadcast receiver (tuner) for TV reception, and a programmable clock (timer) for unattended recording of a television channel from a start time to an end time specified by the user. These features began as simple mechanical counter-based single-event timers, figurine articulée dbz but were later replaced by more flexible multiple-event digital clock timers. In later models the multiple timer events could be programmed through a menu interface displayed on the playback TV screen ("on-screen display" or OSD). This feature allowed several programs to be recorded at different times without further user intervention, and became a major selling point.
