DVR stands for Digital Video Recorder, and it usually requires a DVR receiver, along with standard TV set and broadcast service (satellite or cable). A DVR receiver contains a hard drive and is computerized in order to permit the user to perform a number of functions with the broadcast programming that they subscribe to. Normally, up to 2000 hours of TV programming can be recorded to the DVR receiver, with no videotape. Used in conjunction with the on-screen program guide, programs can be scheduled to be recorded for 9 to 14 days in advance. The playbacks can be set to skip recorded commercials, replayed, fast forwarded, rewound, paused, etc. Slow motion effects are possible with DVR also. Both Dish Network and Direct TV offer DVR service with a DVR receiver.
