Audio not correct

[totya]

Hi!

My English is poor, soory.

Old problem with DVD-RB : (output) audio tracks not equal with original.
I'm probe many DVD...

Example :
Good audio from original (ac3 file), size is : 574 778 624
If I'm converted to DVD-R with DVD Shrink, size is same (good).
If I'm converted to DVD-R with DVD Rebuilder (with CCE or ReJig) this audio size is not good, size is 574 777 280. I think, this is error, cause of audio/video desynchronization.

This is old bug, and latest v0.56 version too bad.
This is big problem.
Many users reported this problem.

Thanks!

Can you give me examples of movies in which this happens? I did several tests in which I reencoded movies and then demuxed the audio from each after the fact... the audio in my tests was always the same length.

Hi!

Very thank you - your answer.

My English is very poor, sorry!

Well, this problem is stay, and very often occur. (most always!). And my friend too say this.

Example? Ok, last compressed film name is "The Watcher".

My detailed steps.

1. Ripp to ISO with latest DVDDecrypter (v3.2.3.0). The result is error free.

2. With DVD shrink (latest v3.2) , Reauthor mode, only move, I removed unnecessary audio and subtitles from movie, and the result to ISO.
This movie, remain audio : English(80) and Hungarian(81), and few subtitles.

3. DVDRB (latest) use (8 pass - vaf + 7pass)

The Result :

Original (80) size is : 310 949 632
Converted (80) size is : 310 948 288 (BAD!)

Original (81) size is : 312 196 864
Converted (81) size is : 312 196 864 (Good!)

Else, all subtitles is equal, compare - ok.

I think the (re)mux function is not good.

My CCE is SP, v2.67.00.23, eclcce is v1.7b, Avisynth is latest official v2.54, dvd2avi is "MPEG2Dec3dg.dll" v1.1.0 (the "MPEG2Dec3dg.dll" v1.3.0 and the latest DGMPGDec v1.12 not compatible with RB 0.56)

This is very old error. I wonder, that for you is good.

Thank you (else this is very nice program) :

Hi!

Sorry my poor English.

My region is always "2". My films tv system is 99.9% PAL.

Certainly, the source is (original size) the DVD-RB source - the DVDShrink output.
Else the DVDShrink output always good.
But ok, I see the first decrypted (DVDDecrypter output) and compare with DVDShrink output.
The result : all audio file equally (binary compare ok, length is ok) demux with vobedit latest.

Demuxed dvd shrink output :

2004.08.28. 12:08 348_737_536 VTS_01_1.80.ac3
2004.08.28. 12:08 149_458_944 VTS_01_1.81.ac3
2004.08.28. 12:08 149_458_944 VTS_01_1.83.ac3

Demuxed first decrypted (DVDDecrypter output) :

2004.08.28. 11:50 348_737_536 VTS_01_1.80.ac3
2004.08.28. 11:50 149_458_944 VTS_01_1.81.ac3
2004.08.28. 11:50 348_737_536 VTS_01_1.82.ac3
2004.08.28. 11:50 149_458_944 VTS_01_1.83.ac3

These length is equally, and binary(!) equally.

Well, this error is very old, and big, if I want correct audio streams, I need demux and remux...
Long ago, I'm say, the DVDRB not working from mounted ISO (and I'm say solving), and really, the developers corrected this problem...I'm not say "stupidity". This "audio different error" is really error.

And idea, i see the "DVD ReBuilder: Known Issues" web page.:

8.
Audio drops out
Status: Open

I think, this possible "audio different error", but not sure (!).

Thanks

@Totya,

I found this error. In some circumstances, when the last sector of a VTS was audio, it was not being flushed properly to the output VTS. It definitely wouldn't be the cause of any audio dropouts -- as it would only happen once in an entire movie and only as the last bit of audio at the end of the credits.

It will be fixed in v0.57.
