Nero 9 sounds like a dog version, according to what I've been reading. There is no BD plug-in, and the v8 plug in won't work. BD authoring is still there, as an extra $$$ plug-in.

Works with 2.75 now. Thank you very much for the fix.

Since Nero 9's filters are once again accessible (as opposed to Nero 8's being locked) through direct show, do you have any plans to incorporate usage of these filters into EAC3to?

I would love to be able to upgrade my version of Nero. I am still using Nero 7, simply because I want to retain full use of your fantastic application. It just seems a shame to not be able to replace an entire multimedia suite due to this.
try installing both versions

How do I determine which playlist contains the correct movie? I ran eac3to and got the following results: Both indicate they are the same length, but use different m2ts files.

Check out some of the "different" M2TS files. It's more than likely different languages in the movie titles etc.

Any integer to integer bitdepth reduction (e.g. 24 -> 16) is performed by doing standard TPDF dithering.

Is there a volume difference? You could compare output to the ArcSoft decoder to find out whether the eac3to decode or the GraphEdit decode is correct.

Not at this time. Maybe later... AFAIK, you can install Nero 7 and Nero 9 at the same time, btw.

I'm not sure about these feature wishes. There are a lot of channel manipulation features I could add, if I knew the exact matrix or dematrix maths. Maybe I'll find a way to do this properly, maybe not. Can't say right now...

This movie seems to have multiple angles. This is usually used to encode different languages in a space saving way. E.g. credits in English, French, German etc. Usually angle 1 is English, but there's no guarantee for that, so you better check out the different m2ts parts yourself to find out which angle is which language (as jj666 already said).

Actually it's not that simple. Everything depends on what the studio did. Here are 3 very different DTS-HD High Resolution examples:

Code:
Example 1, Basic Instinct (Blu-Ray)

+ DTS-Core
  - frameSize            2012
  - DTS-ES               +
  - channelNo            6
  - lfe                  1
  - channelDescr         6.1
  - samplingRate         48000
  - bitDepth             24
  - bitrate              1536000
  - extAudio             XCh
  - samplesPerFrame      512
  - copyHistory          1
+ DTS-HD
  - fullSize             2040
  - headerSize           28
  - refClockCode         1/48000
  - frameDurationCode    1
  - activeMasks          [1], [[1]]
  + Asset [0]
    - fullSize             2012
    - headerSize           10
    - corePackets          Core+XCh
    - extSubStrPackets     XBR
    - bitResolution        24
    - maxSampleRate        48000
    - totalNumChannels     7
    - activeSpeakers       C L R Ls Rs LFE Cs ($1f)
DTS Hi-Res, 6.1 channels, 0:00:14, 24 bits, 3093kbps, 48khz
(core: DTS-ES, 6.1 channels, 0:00:14, 24 bits, 1536kbps, 48khz)
This has a core with 6.1 discrete channels. The DTS-HD extension contains additional bitrate for all 6.1 channels. So if you extract the core, you lose bitrate for all 6.1 channels. This example matches nautilus7's explanation.

Code:
Example 2, Herbert Grönemeyer 12 live (HD DVD)

+ DTS-Core
  - frameSize            2012
  - DTS-ES               +
  - channelNo            5
  - lfe                  1
  - channelDescr         5.1
  - samplingRate         48000
  - bitDepth             24
  - bitrate              1536000
  - samplesPerFrame      512
  - copyHistory          1
+ DTS-HD
  - fullSize             1400
  - headerSize           28
  - refClockCode         1/48000
  - frameDurationCode    1
  - activeMasks          [1], [[1]]
  + Asset [0]
    - fullSize             1372
    - headerSize           12
    - corePackets          Core
    - extSubStrPackets     XXCh+X96
    - bitResolution        24
    - maxSampleRate        96000
    - totalNumChannels     8
    - activeSpeakers       C L R LFE Lsr Rsr Lss Rss ($84b)
DTS Hi-Res, 7.1 channels, 0:00:16, 24 bits, 2605kbps, 96khz
(core: DTS-ES, 5.1 channels, 0:00:16, 24 bits, 1536kbps, 48khz)
This example has a core with 5.1 discrete channels. The DTS-HD information contains a channel extension to 7.1 and a sample rate extension to 96khz. But there's absolutely no added bitrate in the DTS-HD block for the 48khz version of the 5.1 channels. So if you extract the core, all you lose is the two added channels and 96khz, but you don't lose additional bitrate for the 5.1 channels (unless you want 96khz and count the added 96khz bitrate).

Code:
Example 3, House of 1000 Corpses (Blu-Ray)

+ DTS-Core
  - frameSize            2012
  - DTS-ES               +
  - channelNo            5
  - lfe                  1
  - channelDescr         5.1
  - samplingRate         48000
  - bitDepth             24
  - bitrate              1536000
  - samplesPerFrame      512
  - copyHistory          1
+ DTS-HD
  - fullSize             1740
  - headerSize           32
  - refClockCode         1/48000
  - frameDurationCode    1
  - activeMasks          [1], [[1]]
  + Asset [0]
    - fullSize             1708
    - headerSize           13
    - corePackets          Core
    - extSubStrPackets     XBR+XXCh
    - bitResolution        24
    - maxSampleRate        48000
    - totalNumChannels     8
    - activeSpeakers       C L R LFE Lsr Rsr Lss Rss ($84b)
DTS Hi-Res, 7.1 channels, 0:00:14, 24 bits, 2864kbps, 48khz
(core: DTS-ES, 5.1 channels, 0:00:14, 24 bits, 1536kbps, 48khz)
Here you can see that the core contains 5.1 discrete channels. The DTS-HD part of the track contains both a bitrate extension (XBR) and a channel extension to 7.1 (XXCh). So if you extract the core, you lose the back channels and also you lose additional bitrate for the 5.1 channels.

Basically, if you want to know what you'll lose by extract the core, you should use the undocumented "-logdts" switch and then check out which extensions are stored in the DTS-HD blocks. If you strip off XCh or XXCh extensions, you're losing additional channels. If you strip off the X96 extension, you're losing 96khz. If you strip off the XBR extension, you're losing additional bitrate for the 5.1 channels. If you strip off the XLL extension, you're losing Master Audio. XCh, XXCh and X96 extensions can be contained in either the core or in the DTS-HD blocks, while XBR and XLL extensions can only be contained in the DTS-HD blocks...

I see. Thanks

But in the last example you say:

So by looking at this example, is the only information stored in the HD extension is the extra channels (XXCh)?

Thanks for the great explanation BTW.

Code:

  - channelDescr         5.1
  - samplingRate         48000
  - bitDepth             24
  - bitrate              1536000
  - samplesPerFrame      512
  - copyHistory          1

  - fullSize             716

    - corePackets          Core
    - extSubStrPackets     XXCh
    - bitResolution        24
    - maxSampleRate        48000

Yes, indeed. Only the extra channels are added by the -HD extension.

Great, so since my set up is 5.1 all I am getting is the core track... oh well.

Thanks for the help.

Only the header of first frame are read. And the data are previsions:

We know the FrameLength (must be constant) and the FileLength then can have:

Frames = int(FileLength/FrameLength)

Each frame have 1536 samples, at 48000 Hz each frame have 32 ms then:

Duration = frames x 32 ms.

It's not so bad. Look, if this wasn't a DTS-HD track, both the 5.1 channels and also the XXCh extension would be in the core. In that case the XXCh extension would eat away bitrate from the 5.1 channels. In other words: The 5.1 channels wouldn't have full 1536Kbps. Instead you would maybe have 1200Kbps or something like that for 5.1 and the rest for the additional channels. But thanks to DTS-HD the XXCh extension could be moved to the DTS-HD block, so the full bitrate of the core could be spent on 5.1. So you should have a really good sounding 5.1 core.

Yes, exactly that. In fact, SSRC includes this option (in 2-pass mode, of course) so maybe you could use existing code.

You don't know until fix the full stream. You have only previsions:
Like NotFixedDelay is 0, the first header begin at first byte then a correct ac3 stream must have all frames ok, until the last truncated by a buggy video editor.
Quote:
(the video has 1-2 overlapped frames each second)
The video issues isn't relevant for audio.

nvm then, deleted these entries

but wheres that goddamn delaycut thread to be found? search engine is bs in that case and searching with strg+f for "delay" also didnt lead me there 20 pages in the audio section.
so at least dont be surprised questions are asked here.

heres another sample similar to that of robocop, another h264 1080i50 movie. I also have sync problems when slowing down that one, tried it with and without the gaps file. the runtime of the original video is 1:26:58, so the slowed down version should be about 90,7 minutes. with gaps file usage the length is ~1:30:05 (or similar), without gaps file 1:30:36, which also is a little off.

Instead you would maybe have 1200Kbps or something like that for 5.1 and the rest for the additional channels. But thanks to DTS-HD the XXCh extension could be moved to the DTS-HD block, so the full bitrate of the core could be spent on 5.1. So you should have a really good sounding 5.1 core.
That's a good way of looking at it, I was more dissapointed with the fact there was no HD data attatched to the core. It's no big deal though, I will enjoy it regardless.

Thanks again for the help.
