ONLY FILM THAT AUDIO was REMASTERED was by COMPANY WHO REMASTERED NBNW for WARNER was MPK, under DEI supervision, with EROS!!

But since then THE COST VALUE!! deterred them from doing it..

AVERAGE hindi dvd consumer, either wana buy $2-3.99, or 2 in one, for $4-5 bucks, or KHNH for $20 :nopity: :bangbang: :stupid:

I agree. What good is a DTS track on most Indian DVDs? First let's get some acceptable quality video, then worry about icing like DTS.

The sad fact is that we will never have good dvds unless some Gora company takes over.

Also, when a Dolby Digital film is played back in a hall without a DD reader, it doesn't play the front channels in digital. I don't know where you got the idea. The system reads the optical analogue Dolby SR information and plays the film in either mono, stereo or 4-channel analogue Dolby Stereo (the most common).

Dolby Stereo SR is an analogue surround system despite the name. SRD is not a standard term, just a confusing abbreviation by some theatres for 'surround'.

Thanks Aryan for the clarification/ correction.

How I say that front channel sound can still be Digital:

This is what AMC theatres in Canada told me and I found similar thing mentioned at Dolby site.

AMC theatres don't have Dolby Digital, but they claim it to be, still a Digital sound and coming from front channels only. Dolby site said similar that their new encoding process allows for Digital Sound from DD prints when the theatre is not equipped with Dolby Digital. (But, may be it has to have a Dolby reader??)

I guess if the cinema lacks surround speakers and amplifiers, but for some weird reason invested in a DD reader, then yes, they could just play the front channels in stereo with DD decoding. Dolby Digital is like MP3, merely a coding decoding (codec) system - how many channels you get and the quality of presentation would depend on speakers and amps as well.

This is an exception and not the norm.

I was talking of AMC theatres where their default audio is SDDS. Hollywood films (SDDS) play with all the bang from all 8 or 9 channels where as DD prints give no surround at all and the bass is somewhat muted. DD films don't have the same bang. They say, it still is Digital Sound??

SDDS-8 is very rare and only equipped in some theaters. SDDS tracks are almost always encoded with 5.1 channels.

Last time checked Dolby stereo is still analog. I don't know why AMC wants to call it digital. :baaa:

SDDS is either 6 or 8 channels depending on the filmmakers' choice. There is no 9 channel version. The speaker positions are a bit strange. Unlike Dolby EX and DTS-ES, in SDDS-8 there are 5 channels behind the screen, 2 surrounds and 1 sub. In todays tiny multiplex halls, having 5 channels in front is really an overkill, IMO. DTS-ES and Dolby-EX instead provide 3 channels in front, 3 surrounds and 1 sub.

If AMC hall has been equipped with surround speakers, then I don't see why they are presenting DD in 2-channel digital - or even 2-channel analogue for that matter! It should either be 5.1 DD or 4.0 Dolby Stereo. DD contains enough bang for most audiences - SDDS doesn't really have more bang, just less compression (2:1) than DD (10:1). Whether it is DD or SDDS 99.9% of people won't be able to tell the difference. Imagine going on the street and asking people to guess between an MP3 and CD.

Either something strange is going on in the projection room, or the AMC operators need to enlightened.

But then again SDDS is the only true rival to DTS. I saw Gladiator in all three systems and I was amazed how good SDDS sounded but of course DTS got my vote.

A few years ago a multiplex in Singapore used to show movies in DD with the surround speakers softened. It didn't make sense, a rocket would fly past my head fizzle out in the rear!!

I searched through an old zulm thread, where AMC and Dolby sound was discussed. It may not have been conclusive then, but I guess it is conclusive now that the back up sound is not Digital, contrary to the claims by AMC official replies.

Here are some excerpts from that thread:

Rana,
is this text you are refering to from Dolby?
Quote
Dolby Stereo SRD is a new 35 mm format providing both four-channel analog and six-channel digital optical soundtracks on the same print. Film industry representatives attending the demonstrations were favorably impressed by the overall sound quality and the discreteness of the digital soundtrack's six channels, and the compatibility of single-inventory SRD prints. Special demonstration material in both Dolby Stereo SR analog and Dolby Stereo SRD digital was played, as were reels of several recent feature films re-mixed to take advantage of the new digital track's six-channel format.

Thanks Ganti for the link.

The text I was refferring to was from Dolby site, as well, but from a different text page.

The text and the link that you gave, seems to be more recent. According to this, the same recording is used which is capable of being decoded into full blown 6 track digital or 4 track (digital/ analog??). Obviously, theatres may have a 6 ch decoder or a 4 ch decoder. To me it looks like, AMC theatres have a 4 track decoder which provides Left, Right, Center, and "Subwoofer or perhaps mono surround" channel. Actually, this is what the theatre attendant had also told me that SR-D is mainly a Front Speaker sound. Whether it is digital or analog, it is still not clear to me.

Yesterday I got Bytown's owner/ manager on the phone. During the long chat, he clarified that SRD is not Dolby-Digital as claimed by AMC.

He also mentioned that theatre with Dolby Digital but poor accoustics may sound worst than a theatre with reg. audio but good accostics. That's why he is reluctant to change his audio, as the present surround system in his theatre sounds really good. Moreover, DD costs a lot; if you get DD, you have to upgrade the speakers and adjust the accoustics. Otherwise, it will be a mess. Also, the kind of art movies shown in that theatre, Reg surround is adequate.

Not quite. AMC still hasn't acknowledged that SR-D is not Dolby-Digital.

Apparently SRD was name Dolby was using circa 1991 (contrary to my earlier statement) to indicate prints that contain both analogue Spectral Recording and Digital on the same print - which is the standard today. I remember Dolby going through phases of different names for the digital system for cinema and home - and finally settling on Dolby Digital for both. For the sake of this discussion, Dolby SRD means 5.1 Dolby Digital.

Also, just to clarify - Dolby SR (Spectral Recording) (1986) is an analogue surround system with the same number of channels as normal Dolby Stereo (1977) i.e. 4 channels (left, centre, right and mono surround) but with a different (better) noise reduction system than Dolby Stereo (A type NR).

Dolby SR-D is indeed an old acronym for Dolby Digital. There are old Dolby trailers that have DOLBY stereo Digital logos, nowadays its just DOLBY DIGITAL or surround EX. But many filmhandlers still use the term SR-D for DD.

I'm bit confused again.

AMC official reply last year clearly stated that they don't have full fledge Dolby Digital. Dolby Digital prints get Dolby SRD sound that is DIGITAL, but it's mainly front channels

I did happen to watch a few films in Dolby Digital theatre as well as in AMC theatre where it was Dolby SRD. Dolby SRD didn't have any action from rear or side channels, Doly Digital presentation at Famous Players or in Odeon Cineplex did.

You can check at any AMC theatre. Right behind the ticket counter they have a listing of the films and their audio format. They are listed as DD, DTS or Dolby SRD. If you ask them, they will tell you that Dolby SRD is front channels only.

Some trailers also just say Dolby. Probably SRD was thought to be a good acronym to indicate that the film is released in Spectral Recording and Digital on a single print - while what matters more to the audience is whether the presentation they are watching is in Digital or SR.

MAINLY front channels? I think that is the perception some people have of 4-channel analogue Dolby (SR or A). Compared to digital, yes, it would sound weaker and less directional. But I certainly don't buy it that they are playing 2-channel digital. It doesn't make any sense! There were theatres here around 1996 that used to indicate SRD when they meant Dolby Stereo.
