No 5.1 Sound

[bunraku]

Hi

Just got a new DVD Burner today and using shrink to copy a DVD and also to burn.

However i don't seem to be getting 5.1 sound from the copies.
It's more like 3.1 with no sound from the rear speakers.

Any idea why?

Thanx

Hi and welcome to the forum, runraku!

DVD Shrink don't do anything with the sound - just an ordinary copy of the sound tracks.

Have you tried to play the original DVD on your system and does that work?

Any chance you have select a 2 channel track in your backup instead of the 5.1 sound?

The back channels, as you may have observed, are not downmixed by default in DD 5.1. In fact, they are silent unless something is actually encoded in them (like something happening behind you).

This is nothing to worry about.

But there should be something happening.
I used the phantom menace as a test.
No probs with the original'but no backround sound with copy.

Can i ask something?

I've used an original of Goddfellas as an example.
Look at the 2 images.

When i originally open the disc and it scans it i see unticked sound options to the right.

Notice it says the size will be 4435mb.

However in image 2 i have ticked the boxes and instead of increasing in size it

So it's as if unselecting the options is the correct thing to do to add 5.1.
I would have selected these the time i tried it and therefore removes the 5.1 rather than adding?

What has happened when you include more audio tracks is that the amount devoted to video has changed. Before, you had 4435Mb at 79.2% compression - not bad. Now, you have 3260Mb at a whopping great 58.2% compression and it will nto look as good.

In #1, the total (video, audio and subtitlers) devoted to the movie was 4419Mb - this was mainly video with 1 audio track (the 5.1). Now it's 4424Mb but a much higher proportion of that is audio (the other 5Mb have been stolen from the menus, which have degraded in video quality as well).

So, in summary, no problems here.

Perhaps you only kept the AC3 2ch soundtrack.

A couple other things to keep in mind:There is an option in DVDShrink -
Edit --> Preferences --> Output Files (tab) "Logical remapping of enabled streams".

For example, if the DVD audio tracks are:

Stream 1 = AC3 5.1-ch English
Stream 2 = AC3 2-ch French
Stream 3 = AC3 2-ch Italian
Stream 4 = AC3 2-ch English

If for example, you decide to keep Stream 1 and 3, and "Logical remapping of enabled streams" is on, DVDShrink will actually move Stream 3 up to become Stream 2. So if you select French at the DVD's audio menu, you'll hear the stereo Italian version. But if you select the Italian version from the menu, you won't hear any audio.

Generally speaking, "Logical remapping of enabled streams" should be OFF when doing a Full-Disk Backup, however if you're using the Reauthoring function (Main Movie Only) you'll probably want to remap the streams so you can easily select them with your DVD players remote.

Ok thanx guys.

I burned with Clonedvd2 rather than DVDshrink and got the sound ok.
Let me work on it!!

@Taelon - Logical Remapping is always on in re-authoring mode. See the FAQ in my sig.
