Despite the superior video and audio features of DVD players and other devices, the VCR's essential functions probably means that we'll be using them for many years ahead. The traditional VHS format still affords benefits to a large number of consumers. It's a low-cost format which allows individuals to watch and store video content as they wish.

VCRs need at least two "heads" to work. One head reads the magnetic impulses on the videotape and begins the conversion to a signal to present on your TV. The other head is for recording. It places magnetic impulses on a tape for playback later. Four-head models offer better playback and recording, both at the standard speed (two hours on most tapes) and extended play speed (six hours on most tapes).

If you are starting a home theater, or if you just want to hear the stereo signals from broadcasts through your stereo system, you'll need a Hi-fi stereo VCR. The Hi-fi models add two extra audio heads for stereo playback that can approach the quality you get from a CD.

Using standard left-right RCA audio jacks, you can connect your Hi-fi VCR to your stereo system's auxiliary inputs to enjoy movies and TV in stereo. If you're ready to take the next step in sound quality, you can get surround sound by using a receiver that can decode Dolby Pro-Logic (the standard for most rental movies).

If you have a high-resolution source such as digital satellite or digital cable, you may want to consider Super VHS compatibility for your next VCR.

The format delivers 60 percent higher resolution than standard VHS. That can make a big difference when you tape a movie from a digital source. "I can get what approaches pre-recorded quality using S-VHS to tape digital satellite programs," says Brewer. "And again, the sound reproduction is fine." (Note that a standard VCR can't play a S-VHS tape.)
