Can a analog video cassette recorder record from a digital television?

VCRs do NOT process digital signals, analgue is the only language they understand. Therefore, you need to place before the VCR a device that has a digital tuner plus the ability to convert digital signal to analogue.

Examples of such devices are a cable / satellite set-top box, a digital to analog converter box (the converter box ONLY works IF your digital TV feed is coming from an over-the-air TV antenna, not through underground cable), and a stand-alone DVD disk recorder "with a built-in digital tuner".

Whichever tuner plus converter device you have, connect either S-Video or Composite Video AND RCA (red and white) audio output of the device to the input sockets of your VCR. Make sure that whatever "types" of video and audio connections you make are available on both ends, as output on your tuner/converter device and input on your VCR.
