- You are of course aware that a VCR does not record "off [from] the TV". Let's
- say "record from the cable" or "record from the antenna", or, generically,
- "record from the RF input".
-
- That nit having been picked...
-
- - are you certain that the VCR has MTS stereo as well as VHS HiFi ? I've
- never heard of a HiFi VCR that didn't have MTS... but I suppose it's possible.
- In the absence of an MTS stereo tuner, the VCR won't record stereo from its
- RF input. And of course without stereo, there's no surround either.
-
- - MTS VCRs (like MTS TVs, and stereo tuners for that matter) often have a
- "stereo/mono" switch. Make sure this is in the "stereo" position.
-
- - Make sure that the "stereo" or "MTS" indicator is lighted when recording a
- program that's in stereo. (The local tv station may not be sending it in
- stereo. If no stereo, then no surround. Or, some cable systems don't provide
- stereo, even though the off-the-air signal they're relaying is in stereo.)
-
- Given all of that, your VCR should be recording stereo from the RF input.
- There is no special trick to recording surround sound -- if you record
- stereo, you're also recording any surround information that's along for the
- ride.
-
- - on playback, check for stereo effects. Note that very few stereo VCRs will
- provide MTS stereo via the RF output jack. (I'm tempted to say "none", but
- since I don't have a definitive list of the features of every VCR ever made, I
- won't go out on that limb!) To get stereo playback you need to use the "audio
- line out" jacks on the VCR, and feed these to a stereo amp + speakers, or feed
- the video and audio line jacks to the line inputs on a stereo tv or monitor. If
- you're not sure, the best way to check for stereo sound effects (but not
- surround) is with headphones. (You are probably doing this part right, since
- you're getting stereo and surround from pre-recorded (movie) tapes; I just
- mentioned this to be complete.)
-
- Finally...
-
- - most of the surround effects I've heard from tv programs are pretty subtle.
- Are you certain that they're missing? eg on Star Trek:TNG, the "surround
- track" is pretty much limited to things like the engine "rumble" on shipboard
- scenes. On Batman: TAS, I've noticed the surround track being used for crowd
- noises and the like, and not much else. (Commendably imo; having the apparent
- source of sounds bounce all over the room can be damned distracting.)
-
- The thing to do is to find a movie that's being broadcast that you know was
- done in surround, tape it off the air, and compare it to a rental tape.
