24/96 PCM audio again

pjb2222 wrote on 10/22/2003, 2:38 PM
Recent postings suggested using IfoEdit to make 24/96 DVDs playable. I can burn a 24/96 DVD using DVD architect. It plays fine using Cyberlink PowerDVD, which reports Audio: LPCM 2.0 4608 Kbps. (16/48 DVDs are 1536 Kbps). When I play the same DVD on my Toshiba SD110E stand alone DVD player, it plays OK from the start of the DVD. But, if I stop it, fast forward, or use the menus, the sound goes, and it plays at double speed.
I looked at my .ifo and .vob files using IfoEdit and VobEdit. All the audio is flagged as being 16/48!
When I used IfEdit to change the lines to 24 bit and blank sampling rate, the DVD played with exactly the same problems in my DVD player, but Cyberlink Power DVD reported "no audio".
Any suggestions?

Did you check

Yes, that's why I posted the question, as the answer there doesn't work for me.

Hi Patrick,

I figured out the problem on the last post. You say that the VOB file says 16bit? That could be the problem. You may have had DVDA set to re-encode the audio and the bit depth was changed to 16 bit. I used a 24/96K file and the VOB came out as 24 bit. The IFO and BUP files said 16 bit. All that was needed is to change the IFO and BUP files. That goes for all the files. If you are using multiple Video Title Sets (VTS) you will also need to make that change in multiple locations in the VIDEO_TS.IFO and VIDEO_TS.BUP files. Once for each VTS entry. Just a thought...let me know what you find.

Patrick,

I just looked at the IFO files again and found the problem. In the VMG overview section in the VIDEO_TS.IFO file, there is another reference to the VTS sets in the VIDEO_TS folder. You need to change the values for bit rate and sampling there too. I'm really sorry, I missed it. It looks like the VMGM section in this file is for the main menu attributes not the VTS. The change must be made in the VMG overview...the screen that loads first in IFOedit. The same goes for the VTS.IFO. Make the change on the first screen or VTS overview. It will update the information table too. Forget about going into the MAT table.

Ron,
Thanks for your help. Unfortunately no joy. Editing the ifo files makes the DVD unplayable by Power DVD on the computer (it reports no sound), but makes no difference to the problem on the stand alone DVD player.
Incidentally, I checked with Vobedit and the audio files are correctly showing the flag 1, for 96k, apart from the menu audio flag, but I don't have any menu audio.

Patrick,

Sorry to hear that. The only other thing I noticed was I had to use Music compilation mode when authoring in DVDA. Then playback worked fine with 24/96. If I did not it wouldn't play like you said on your PC. I didn't try the stand alone player in that mode. The disks I've created with DVDA using Music compilation mode work fine on both my PC and several DVD players I have. I use WinDVD 5.0 and I tried 4.0 too and that worked. I just upgraded to WinDVD 5.0. Don't ask me why this is so. It doesn't make sense. I've compared the structure of the files to one made with Scenarist and all looks well after the changes I've stated. I have Scenarist Pro too and it works great but it is a bear to figure out and you have to create all the graphics for the menus yourself...very time consuming. I don't use it much any more. Programs like DVDA and Uleads DVD Workshop work great for me. DVDA has support for 24/96 and progressive video where DVD Workshop does not. Not yet that is!! Give Music compilation a try if you have not. Then make the changes. Good luck!

I can't get DVD architect to produce a 24/96 music compilation. It renders my 24/96 wav file as 16/48. I can't see what settings to adjust to stop it doing this.

Have you actually told DVDA not to recompress when rendering? It's in the optimize dialog...

When I try to make a "music compilation" the compress box is automatically ticked, and greyed out. There doesn't seem to be any way of forcing DVD architect not to compress. Does not seem to apply to any other types of DVD. Even picture slideshow does not force recompression.

I can insert 24/96 audio in a music compilation and then define LPCM in the optimize menu...

But when I do that it still shows as a yellow diamond, not a green tick. In other words, it is still recompressed. This even happens with 16/48 wav tracks.

When you see the yellow whatever, you can select the item and set audio to "PCM" in a dropdown menu below. If the format is right, you should then get the green tick.

I have done that, and it stays as a yellow diamond. This applies even to 16/48 wav files. The same wav files, in any other DVD architect project, e.g. scene selection menu, are fine, and show with a green tick. Wav files are all captured using Vegas.

Despite the yellow diamond, it does still render a PCM 24/96 file. So I tried. No joy. Just the same as with previous attempts using Scene selection menu.
