| | Posted: | | | | So I have "Mother" (UPC: 097363324744) and the two English Audio choices go like this:
English 5.1 Surround (menu label)
When selected, VLC shows:
A52 Audio (aka AC3) (a52)
English
Channels 3F2R/LFE
48000 Hz
448 kb/s bitrate
PowerDVD shows:
Audio Attributes:
Audio Coding mode: Dolby Digital
Sampling Rate: 48kHz
Audio application mode: Not specified
Number of Audio channels: 6
Bitrate: 448 Kbps
-----
The next label is for: English Dolby Surround
VLC:
English Dolby Surround
A52 Audio (aka AC3) (a52)
English
Channels: Dolby
48000 Hz
192 kb/s
Audio Coding mode: Dolby Digital
Sampling Rate: 48kHz
Audio application mode: Surround
Number of Audio channels: 2
Bitrate: 192 Kbps
----
The present profile says:
English Dolby Digital 5.1
English Dolby Digital 2-Channel Stereo
"Dolby Surround" is not mentioned in the right column for any audio track.
What should the profile say?
Is there a definitive thread for deciding, once you have Dolby Digital, whether you have:
Mono
2-Channel Stereo
Dolby Surround
3.1
4.0
4.1
5.0
5.1
Since our database places a very high regard on accuracy, I'd love to know how to be accurate here. |

Can I use the info from this link to help sort things out? |

| | Posted: | | | | Just from the label it should be:
1. English Dolby Digital 5.1
2. English Dolby Digital Dolby Surround
I don't seen anything in all the other software checks to seriously suggest otherwise, and why make life complicated? These are just the labels we use, a limited number for potentially an even larger variety of sound channels. | | | | Hans |

| | Posted: | | | | Both tools are showing the same audio types as the DVD label.
For the first track: "English 5.1 Surround". VLC shows six channels "3F2R/LFE"; 3 front 2 rear makes the "5" and LFE is the ".1". PowerDVD shows 6 channels and lists them as "Dolby Digital". All three of these are the same.
For the second track: "English Dolby Surround". VLC shows "English Dolby Surround" and PowerDVD shows 2 channel Surround. This track is the old "ProLogic" format where four channels, left, center, right and rear are encoded into two channels. | | | Paul Francis
