DVDShrink - No DTS Track?

[iqwertyi]

Hi,

I've been using DVDShrink for some time and been very successful with backups. But recently with my newer movies, I've noticed that selecting the DTS track only gives me problems.

I typically stip the movie of any other material except for the actual audio and video, and when available, always selected DTS. With some newer movies, I've noticed that after I run shrink and back up with nero the movie plays in a faster speed (as if it's being fast forward) and no audio track. When I re-shrink it with DD 5.1, the backup comes out OK, but I'd like to have DTS.

Now, I've done some searches and someone mentioned "To stop that from happening, you need to select logical remapping of audio". Is this option in shrink? I didn't see where I could check this off.

Thanks.

DVDShrink 3.2 Edit>Preferences>Output Files tab>last check box.

BTW i would reencode movies that have DTS not transcode. but that's me.

[iqwertyi]

There it is. Thanks :)

Can you explain more when you say
reencode vs transcode?

I typically use decrypter first to my harddrive then use shrink to strip out the extras.

If your using reauthor mode you can right click on the title and select default stream then select DTS as the default audio streem. This option is only available in reauthor mode. As far as the movie running fast well thats a new one I've never had that happen.

[iqwertyi]

Yeah, typically, I'd use decrypter first.

Then I use DVDShrink and reauthor. I'd pick the title and drag/drop it to the left and select only DTS track. After it finished backing up, I use nero to burn.

My older DVD's were all fine but newer ones like Collateral, Terminal, and a few others all came out the same. No audio and maybe 2x speed when playing back.

I should mention that this was with 3.1.7 (i think), maybe it's been fixed with 3.2 but I'll try tonight.

Deffinitly upgrade this is most likly the problem. I did spiderman and the terminal as well as pitch black, i,robot, colladeral, LOR ROTK extended version all with DTS and they came out fine with 3.2.

@iqwertyi

I just wanted to point out in 3.2 there is AEC(Adaptive Error Correction) option.
after you click Backup! you will see Quality Settings tab. there you can set Maximum smoothness, smoothness,sharp (default),Maximum sharpness. you would have to do test yourself because no one can come to a conclusion which is a better setting(just too many factors to account for)so please don't ask which is better.do alot of searching

maybe dannyv can point you in the right direction. he would know more then me on that matter.

Most movies can be done with sharp default setting.

If you use a lot of compression for movies lets say over 2:30 mins use smooth setting. This will blur the picture a tiny bit and hide some of the pixalation also If your going to compress a movie that much you should be using dvd-rebuilder and not shrink. Shrink I found is good for 70% compression and above anything below 70% use dvd-rebuilder.

I never found a need to use max sharp or max smooth and never saw much of a difference between sharp default and max sharp. I also could not find much of a difference betweem smooth and max smooth.

AEC is a vast improvement over the older version of shrink. You will see it makes a major difference in the quality of the finished project.

Thanks for the advice. I'll try when I get home.

Here's one I cannot understand.

I did the usual steps I do to backup my DVD's but this time using Shrink 3.2 and checking off logic remapping and burned with nero.

When playing back in my computer (using Winows media and ATI DVD) it still played with no audio and at about twice the speed. But instead of throwing away the disc, I popped it into my standalone DVD player and it worked with DTS audio and at normal speed.

Is it because I don't have dts codecs in my computer? If that's the case, what's a good software that will play DVD's in a computer and play dts tracks?

PowerDVD works perfectly on all audio streams.

cool, I have PowerDVD software (came with a CDR/DVD drive I bought). I think it was PowerDVD XP.

I'll give that a try.

Let us know how you made out.

[iqwertyi]

I don't understand.

I installed PowerDVD Deluxe on my brother's laptop (he watches the DVD's in his laptop) and the video playback is now fine, no longer playing at 2x speed but still no dts audio. Even the subtitles work, but I cannot get audio to play. Once again, it plays fine on a standalone dvd, but my brother likes to watch in his room on his laptop.

I tried to go though the different settings but I didn't even see an option for an alternate track, which I shouldn't since I only selected dts with when i "shrinked" it.

I tried two backed up DVD's that I only did with DTS tracks and no audio. I tried a backed up DVD with 5.1 and that worked fine.

I'm trying to solve this so I don't have to back up two sets of DVD's just for my brother to watch.

When you shrank it you did not define a default audio stream (Please refer to my earler post). To select the stream to play in powerdvd start the movie then right click in the movie screen and select audio language from the list then select the dts track.

@iqwertyi

Does the laptop have a DTS amp? It's not good enough just to decode it, you must have a digital amp. Lots of DVD players (including software ones) can decode the DTS stream, but unless you have an amp, you will get nothing. Nada!

In any event, you will not see the diff on a laptop. Take the DD5.1 (AC3 stream) and it will sound fine on a laptop and, indeed, on a regular TV. IMHO, DTS is for major home cinemas.

Season's greetings

[iqwertyi]

Thanks for being patient with me guys.

Dannyv,

I just realized what you posted earlier. I though selecting the movie alone and going to the reauthor tab and selecting only the dts track was enough. I didn't know I actually had to right-click on the screen and point to audio and select DTS to make it the default audio.


blutach,

I didn't know I needed a DTS amp to play DTS on the laptop or my computer in that case. When I previewed with the DTS there was no audio, but as soon as I selected DD5.1 the audio came up.

The laptop is an IBM T20 or T30 (can't remember now), and my computer is fairly old as well until my major upgrade in a month or so. It's a P4 1.7 Gig with the old motherboard (using Rambus memory).

I think this may be the problem, since it does play fine in my HT.

and yeah, I prefer DTS since I do have a Home Theater setup :)

DD5.1 will always be able to downmix to stereo - it will play in any PC and set top. DTS is another kettle of fish. No digital amp - no sound. This is what is happening. It works on your home cinema cos you have the amplifier and the decoder. It doesn't on the PC because no amp.

If these disks are for PC only, don't bother with the DTS track - it will only take up lotsa valuable space that the video can occupy (not that you'd notice quality drop from low bitrates on a PC anyway). Only take the AC3 track.

And then there's no worry about the default stream. :)

Funny,I watch Fantasia and LOTR movies all the time on my laptop and PC because I have a 1st gen DVD player that wont output DTS to my Onkyo(which I like to hear DTS-CDs on).

It has nothing to do with hardware my buddy,its software.

I use PowerDVD 6,but it worked fine with Windvd 3-5 as well...:rolleyes:

[TheJez]

Just out of curiousity.... doesn't a DVD at least need either a DD-stream and/or a PCM stream to be DVD-compliant ? So a DVD containing just DTS isn't compliant ?

Take care,

The Jez

[blutach]

No - I make stacks of DVDs with just DTS audio. It has its own defined stream number 0x88 or 89.

And Morbo, you are saying what I said - if you can't decode it in your player (H/W or S/W) , having it in your amp won't do any good either. The reverse also applies - if your player decodes it but your amplified can't play it, also "no go".
