It can record and play back a different recording simultaneously. With it you can pause live television and in some cases record more than one show simultaneously. It allows for easy set-up to record a program one time or on an ongoing basis. While once a subscription product available from a small number of companies like Tivo or Replay, many cable companies and satellite systems are now offering the service.
