| Posted - Feb 19 2001 : 2:52PMWhy do a lot of DVD boxcovers state that the film has "5.1 stereo sound" when there is no such thing? Either it has 5.1 digital surround sound or it has stereo sound, it can't be both. Anybody have any idea? [Link] |

Welcome to Adult DVD Talk tess514!! I'm not sure why they do this. I'm guessing it was put there by someone who doesn't really know the difference. These mistakes happen all the time. For instance, ever seen a movie that has the actress's name spelled differently on the box cover than the movie credits? I still don't get that one! - [ invalid url ]  [Link] |

Oneloa - how about this one: The actresses' name is spelled wrong on the cover and she's not even in the movie. I've seen that one happen too.

In most cases, it's just Dolby Digital Stereo. That is, it's a stereo soundtrack encoded into an AC-3 bitstream. The result is sound out of the front left and front right speakers only. I think that whoever does the boxcovers thinks that AC-3 encoding = 5.1, which is false, since AC-3 an audio encoding & compression method (and is capable of containing everything from mono to multichannel sound).I've also found some with Dolby Digital Surround audio, which is just matrixed from the production stereo track. In other words, there's no discrete surround channel and the surround is "faked." There are DD5.0 and DD5.1 titles that definitely have discrete channels and sometimes an LFE channel. The surrounds tend to be nothing more than the music portion of the soundtrack. Sometimes there's directional effects out of the rear speakers, but that's pretty rare in adult titles. In many cases though, the boxcovers are technically incorrect, and the only way to know what you're getting is to put it in the player and see what shows up. - Saki  [Link] |

Maybe the studios should hire our members to do the cover info. It seems we have more knowledge about the contents than they do! [Link] |

I also have a disc that is encoded in 5.1 sound but in fact... if you listen to each of the speakers... only the left and right front speakers are actually outputting sound. I just figured it was another cheezy marketing trick... like the "multiple angles" which are actually just mirror images of the same thing. In other words, you're only getting stereo, but it's encoded in 5.1 (with no sound coming from the center or rears) so they can say "5.1 sound" on the cover... even though it's really not 5.1 sound. Not that it bothers me. I don't really see the point of having porn in 5.1 sound... unless it's a feature-type movie like Flashpoint or something (surrounds could be used for sound effects)... or maybe you could use 5.1 for an echo effect like that Raquetball court scene in one of Rodney's "I Swallow" movies. But in most cases, I don't think 5.1 would really add anything. Plus I'm not sure what it would do to the production costs. [Link] |

Well, if no sound is coming out of the center, left surround, right surround, and subwoofer (i.e. there's no sound encoded for those channels, it's not 5.1--it's Dolby Digital Stereo. It is encoded in AC-3, which is commonly (and mistakenly) referred to as 5.1. I really think it's just a lack of understanding on a studio's part rather than a deliberate lie.I'd agree that it's generally unnecessary, especially since nearly all porn is shot with a stereo mike. But occasionally, it does pay off. The best example I can think of is Andrew Blake's Pin-Ups 2 , which features a 360 degree sound pan--very cool. - Saki  [Link] |

Hey there, If I can add my 2 cents worth, here it goes. Most of the movies that are used to go to DVD are Beta Sp split track, vocal in right and music in left, or whatever, but regardless something has to be done to it to get it more to standards of what people expect on the DVD's. You are correct in assuming that alot of people really don't understand unless it is recorded originally 5.1 it can't be 5.1 on the finished version. Only phantom, dolby digital surround, or AC-3, all the same thing, is studio faked surround sound to give you the better sound quality on the DVD. Some people don't fully understand this, but as you the viewers, reviewers and consumers keep pointing it out to the labels, they will get the message, our eyes and ears are open so give us the true facts on the boxes.Kat  [Link] |

Hey Saki,Yes... I guess it's not really 5.1 by definition since you are not actually getting 5 channels of sound (plus an LFE). The thing is, with the disc in question, my theater amp says that it is receiving and decoding multi-channel sound (i.e. the multi-channel decode light goes on) but I'm only getting stereo. Maybe the "multi-channel" indicator on my amp (Sony DRE945) just goes on when it detects AC-3 encoded sound but not necssarily 5+ channels... not sure.  [Link] |

Hi Takeo, That is correct, the light will go on with both AC-3 and PCM as it is multi channel, but not 5.1. Ahh, the wonders of modern technology.Kat  [Link] |
