There is no way to remix a DOLBY SURROUND program to pure stereo!) So although the original dialog of a surround track has been dubbed on a separate track it still doesn't become stereo. | | | Martin Zuidervliet

I always check these tracks with PowerDVD in Media Files mode, I've never seen it disagree with my system (Denon DVD-1940, I think, to a Sony STR-DG910 receiver) in the matter of stereo vs. 2.0 surround.
I forgot about that, but you're right: PowerDVD in Media Files mode is really helpful. This indeeds identifies both these 'Hot Shots! Part Deux' audio tracks as "surround" (which it doesn't in "regular" playing mode):
Now how to explain this to the thirteen (out of fifteen!) people voting for the surround to stereo-change?  I'm intrigued! I just recently started using PowerDVD, so I am not too familiar with how it works. (I have PowerDVD 8.0 Ultra Version). How do I play movies in Media Mode? I've played with the program quite a bit these last days, but can't for the life of me figure out how to run in "Media Mode". Help greatly appreciated, as this would help immensely in determining audio tracks!  | | | Berak

| | Posted: | | | | This interested me as I have a version of HS part 2 (5-039036-006118) and PowerDVD 7.0.
In "normal" mode the Audio shows up as Dolby Digital 2.0 192 kps.
But in "Media files" mode the Audio shows up as Dolby Digital 2.0 Surround 192 kps.
Why is thsi? | | | | Chris |

| | Posted: | | | | It's ever so strange, isn't it? Back in version 4, it would report the surround tag in both normal and media files mode, but ever since version 5 it only does it properly in media files mode. Quelle odd! |

| | Posted: | | | | PowerDVD may say that an audio track is flagged as surround but it does not necessarily means it is, as "shaumi" so elegantly explained in his first remark of his comment. | | | Martin Zuidervliet

The only thing the Home Theatre Receivers and/or programs like Power DVD can tell You is what flag is set on the DVD. And these flags are often not correct. They can tell you the flag on the DVD, and they can tell you the flag for the sound file proper. While the DVD flag is often wrong, the flag in the sound file is usually correct... if it's set. (It sounds like PowerDVD is reading the latter in media mode and not looking at the .IFO files containing the DVD flag.) Unfortunately, the only software solution that I'm aware of for checking the actual status of the flag on an AC3 track, Azid, requires demuxing it and then running a command-line program. VLC--and probably PowerDVD--correctly show the presence of the Dolby Surround flag, but VLC (I don't have PowerDVD, so I can't speak for it) treats unflagged material the same as stereo-flagged material. (Is it truly a flag if it has three states?  ) | | | --

Commentary Audio changed from 2-channel Stereo to Surround, the movie is used as audio source on the commentary track, and 2-channel Stereo is non existing in modern cinema, the surround flag is always set. | | | | Corey |

2-channel Stereo is non existing in modern cinema I won't speak for "modern cinema" but DVDs can certainly have 2 channel stereo OR surround. PowerDVD (and my receiver) can tell the difference. I've seen it vary from track to track on a single DVD. So in answer to your question: No. The contribution comment may be correct, but based on the comments it would be accidental. | | | | Bad movie?

| | Posted: | | | | Dolby surround works by taking 2-channels and putting info that's the same in both in the center and info that's the same, but out of phase in the surrounds. This doesn't happen by accident. Dolby surround encoding is very common. Theaters went straight from one speaker to 4. TV did have two-channel stereo for a while. Basically, you'll never see anything that's two-channel stereo but not surround except for TV programs, DTV material (which some dubs may be) and music, though most of these are also surround-encoded. |

| | Posted: | | | | THX for opening this thread, I was about to open a similar one AGAIN!!! We had this discussion here so many times. As contribution is enabled again I started with it yesterday and I am also changing all 2-Channel Stereo tracks into Surround tracks. 2-Channel Stereo in modern cinema is almost non existing, the surround flag is always set. And it is also nearly impossible to prove that with each and every DVD / Blu-Ray. it is just a given fact , like 1+1 = 2. A very few tv shows from the 70s and 80s and some music DVds have REAL 2-Channel stereo tracks but that's it. Most people vote yes to my changes and so far such a chnage was never negelcted by the screeners but I have a user right now who is still not believing me (not you Katatonia  ) and will link him to this thread here now. Cannot thank you enough for bumping this up again Also what Ace Of Stevens said was 100 % correct. cheers Donnie | | | | www.tvmaze.com | | | | Last edited: by DarklyNoon |

Is this information really useful to anyone? A modern receiver will adapt itself accordingly. Why not simply make it one option and call it stereo/surround? Problem solved. I'm with this, esp. since I just tried the powerdvd media files trick and at least the disc I tested, still came up Dolby Digital 2.0 192kbs. Did I do something wrong? I hit control+o then went to media files, took vts01,02 and 03 (the 3 biggest so obviouslly the film) and added to list, then played that in powerdvd. But my display didn't change (screenshot text looks different than my default, I'm version 7.0) and all the readings were identical to if I was just playing the dvd normally. I'd love for this to work but first try failed hard. |
