Reauthoring 15 VOBs in new DVDR yet some missing sound

Oceanview2 · Apr 22, 2004

Shrink does a perfect job of copying DVD's but when I try to reauthor creating my own menuless production using 15 different VOB's (like ripped music videos) neither the disc image nor the burned disk plays well on virtual or desktop DVD players respectively. The major problem is that there is no sound on some of the clips. Of course everything sounds fine in the Shrink preview window but the burned image or disc does not present the 15 VOBs with sound as a new DVD. Sometimes 4 VOBs will go silent then the next three will have sound.

I've followed many different guides and tried various techniques with Ifoedit, VOBedit, DVDstripper, Smartripper, DVDdecrypter. But I cannot get a flawless compilation of movie clips to work well straight through with sound.

I've used various media types DVD+/-R and these work great with identical copies or mere removal of material using Shrink, but I am importing VOBs from various sources and trying to create something original (and menuless) with about 15 VOBs and just cannot get it done. The problem is the authoring not the players because the strick DVDR copies work just fine.

Any suggestions?

Check your video clips, what sort of Audio does each have? Are some AC3 then others LPCM ? That could be your problem. Best to convert all to AC3 2ch if any are LPCM

the audio from the different VOB's will be in different streams and your player will stick to one stream and play only that audio if it's referenced in the PGC

example below (info in VTS_PGCITI) for 2 PGC's. The 1st has an audio in stream 1 (0x80) and the 2nd in stream 2 (0x81). The DVD will default to stream 1 and then you will hear nothing when it plays the 2nd Title

to fix it you will need to open the IFO's in Ifoedit and make sure all the audio's are in the 1st stream (0x80) in all the IFO's

it should then look this below

MackemX, I do indeed have the 2nd Audio Stream with nr 1 yet when I double click it (in Ifoedit) I either get "edit value" or "Item is not editable". Can you tell me how to edit that line from Audio Stream 2 nr 1 to Audio Stream 1 nr 0 as you indicate? Thank you.

MackemX · Apr 28, 2004

in the VTS_PGCITI/PGC, double click the decimal value which is 32768 in the example above and it will show the value and allow editing by opening the Edit value window. You enter the value in decimal and Ifoedit will change it Hex which is 8000 for 32768. Change stream 0 to whatever value stream 1 is (32768) and change stream 1 to 0

you must also go into the VTSI_MAT in the same IFO and transfer the Audio settings from Audio 2 to Audio 1. To edit, double click the Audio highlited below and copy the Audio settings

if it get's too messy or complicated for you just email me the IFO's and I'll have a look for you

I appreciate your help on this and hope that what I am trying to do is possible. I (dvdr) burned a fine collection of vobs that works great on all the stand alone DVD players. But I made sure that all those vobs had the same audio format, in this case lpcm. I had only one audio stream and all 14 vobs (dvdr) played fine. What I am trying to do now is burn many vobs with varying audio steams: lpcm and various versions of AC3 5.1 etc. As I mentioned before, when I do this with vobedit and ifoedit there are always two audio steams and half of the burned vobs lack audio on stand alone DVD players. So I have a few questions. Is it necessary to convert all the vobs to the same audio format, whether lpcm or AC3? Can this be done? How? Is it necessary to demux the vobs needing audio conversion then remux them? (ugh) If I follow what you have indicated above could I forgo demuxing?, and would all the varied audio formats come together and work seemlessly on a stand alone player? I am basically producing a menuless main movie with the same number of chapters as vobs (as many as 30) with varying audio formats. My feeble attempts at applying your model have not yet achieved a successful DVDR but I am willing to keep trying if you can assure me that this will work. Thank you.

the quickest and best way I can offer some good advice is that you email me the IFO's after you have reauthored them. I can take a look at them and see what is what but I have a good idea what they will look like at the minute

I could even mod them for you and give an explanation of how I did it so you and maybe others can use it for future reference

p.s. thinking about it, I'm sure you can change the settings in DVDShrink so that it doesn't use the default streams and remaps them itself

I have attached the ifo files. I put together about 21 vobs with varying audio formats and the result is 7 audio streams. I would like to get a DVDR that plays all the video clips with sound on stand alone players. Thank you.

MackemX · May 11, 2004

thanks as seeing it makes it so much easier

what did you use to author the DVD? Was is Shrink as I always thought it created a new title for each PGC you reauthor and this is just one title with 23 chapters

I don't think you can have different audio's within the same PGC and all these VOB's are within the same PGC

do you really need to have them all as seamless chapters?
