But always nice to see that in the end those people that attacked me seemed to be plain wrong.
Donnie Dude, you have a skewed view of the world. Asking for documentation is not an attack. You were the one attacking others as a response to a very reasonable request. Indeed. Had he simply provided documentation, as Ace did, instead of attacking, this would have been over a long time ago. | | | ASSUME NOTHING!!!!!! CBE, MBE, MoA and proud of it. Outta here

Donnie Dude, you have a skewed view of the world. Asking for documentation is not an attack. You were the one attacking others as a response to a very reasonable request. Indeed. Had he simply provided documentation, as Ace did, instead of attacking, this would have been over a long time ago. Well, I seem to be missing something here. I provided about the same documentation that Ace did, he linked to a site that explained it all and I linked to schaumi, who works in the business and knows everything about his issue and he pretty much explained it perfectly, as perfectly as the link does that Ace pointed to. Otherwise there is NO PROOF, as I always said, it is not proovable by any program or any receiver, hence why every receiver or program gives you different results. So either we believe those experts or we do not. I tend to believe them , some seem to not believe them, but without knowing any better of course, They just doubt what experts or expert sides say. So the only "proof" or explanation given to change all the audio from stereo to surround is alink to what an expert on that matter has to say. And that link I surely gave. But we can really end this now, I stopped caring ; I have it all correct in my local now and I am fine with it. cheers Donnie | | | www.tvmaze.com |

| Posted: | | | | I agree the doc that Ace has provided is nothing. And while I have not seen anything to change my opinion over the years, i STILL check each and evry disc either the DVDShrink, my system or BOTH. And for notes i would explain this and cite my results.Which is far better than what is being done, that is genuine documentation for each disc, not just a GUESS based on website...no matter how good or accurate the website might be,.Stay above that kind of lame doc, donnie, don't let the turkeys get you down, just add substantive doc.

Skip I agree with almost everything you wrote Skip, but I think it is impossible to verify this with the equipment we have, hence the votes I got, people stated they have checked , some said Yes and some said NO, so people with different equipment got different results. Conclusion for me is that the opinion of an expert who works in this industry or an expert website is more trusworthy than all our equipment we can use to document this. But as Is aid, I leave all those Stereo audios alone for now in the online database, someone else can deal with it cheers Donnie | | | www.tvmaze.com |

You might still be able to get a copy of DVDShrink...it's free.

I seem to be missing something here. Indeed you are. Quote: I provided about the same documentation that Ace did, he linked to a site that explained it all and I linked to schaumi, who works in the business and knows everything about his issue and he pretty much explained it perfectly, as perfectly as the link does that Ace pointed to. You provided a quote from another user. With all due respect to that user, I have no way of knowing whether or not he actually works in the business and knows everything about the issue. Ace, on the other hand, provided a link to a document from Dolby. When talking about Dolby Digital Sound, I am more than willing to take their word on the issue as it is their technology. I am not, however, willing to take another users word on it. I am sorry if that offends your sensibilities, but we are all just words on a screen and I have no way to confirm that you do, indeed, know what you are talking about. Quote: Otherwise there is NO PROOF, as I always said, it is not proovable by any program or any receiver, hence why every receiver or program gives you different results.
So either we believe those experts or we do not.
I tend to believe them , some seem to not believe them, but without knowing any better of course, They just doubt what experts or expert sides say.
So the only "proof" or explanation given to change all the audio from stereo to surround is alink to what an expert on that matter has to say. I am more than willing to accept what an expert has to say on the issue. Where you and I differ is in what constitutes an expert. If a user gives me their opinion, then refuses to give me any verifiable information to back it up...basically saying, "it is because I say it is." I give that user very little credibility. If, like Ace, they provide verifiable documentation to back up their opinion, I give them the credibility they deserve. Quote: And that link I surely gave. Again, you gave a link to the opinion of another user. While that was enough for you, it wasn't enough for me. Quote: But we can really end this now, I stopped caring ; I have it all correct in my local now and I am fine with it. Actually, this could have ended a long time ago. Unfortunately, you decided to take a few more shots at the people who didn't accept your 'proof'. | | | No dictator, no invader can hold an imprisoned population by force of arms forever.

I think you may have misunderstood what has been going on here. He had been making changes with the notes, "2-channel Stereo is non existing in modern cinema." That's it, no verification method, nothing. That is why the 'turkeys' questioned his contributions. Anyway, I don't know why I even got into this thread as I really don't care about this issue. | | | No dictator, no invader can hold an imprisoned population by force of arms forever.

| Posted: | | | | One last question about this issue. Now that we have an "official "statement" from the Dolby site itself, that the surround data is ALWAYS there, is that proof enough for you, that I can change all the stereo tracks to Surround ? I am not talking about Music tracks and early 80s and before tv-programs Just for movies. cheers Donnie | | | www.tvmaze.com |

Just for movies. Unless Dolby also provides a list, by UPC/EAN, of each disc and what each track actually is then no, it doesn't matter what they say. What was done in theaters isn't relevant to what is done on the discs. Just let the data on the disc rule. If it decodes to Surround fine. If it decodes to DD 2.0, also fine. There are tools (PowerDVD, many receivers) out there that can differentiate between the two. I have any number of discs with both flavors and the tools can tell the difference. Just let the data decide. | | | Bad movie? You're soaking in it! |

| Posted: | | | | hey there Ken, here is the link that Ace_Of_Stevens provided: Dolby SurroundHere is the part that matters in my opinion: The conformed material is then encoded fo DVD as a stereo Dolby Digital (2/0) track with a flag indicating the material is surround-encoded. On playback, the consumer decoder sees this flag and activates the Dolby Surround Pro Logic decoding to reproduce the soundtrack in four-channel surround (L, C, R, S) as the director had intended. The audio bit rate for this track should be at least 192 kbit/s. cheers Donnie | | | www.tvmaze.com | | | Last edited: by DarklyNoon |

| Posted: | | | | That does indicate that the surround data is there when the flag is set, which I don't think is in dispute. The question is whether the flag is always set, which I don't think we've answered. We've seen reports in this thread that it is not always set, so let's examine that further.
For those reporting plain stereo tracks, perhaps some specific examples would help so that we can do some parallel analysis. | | | Invelos Software, Inc. Representative |

| Posted: | | | | The paragraph after that one then goes on about what to do with a stereo track.
"As with Dolby Surround masters, no attempt should be made to create artificial LCRS components. The material should be encoded as a stereo Dolby Digital (2/0) bitstream at the highest bit rate possible (192 kbit/s or higher). In this case the surround flag would not be set."
When I encode audio with Sony Vegas 9 and use the Dobly Pro encoder in it, their are three options for surround. By default it is set to "Not indicated", the other options are "Not Dolby Surround encoded" and "Dolby Surround encoded". |

| Posted: | | | | DVD mfrs are completely incapable of properly setting flags for progressive vs interlaced; I don't see why one would assume they can properly set flags for surround. | | | "This movie has warped my fragile little mind." |
