For some reasons (crap music background lol ) I decided to try to edit one of the VOB files using Ulead Studio. I don't know that software too well but I managed to edit it as I need. To edit it I changed the .vob extention to .mpg. Now I'm at a point when I have a ready project but I'm not too sure how to get it back to the original movie. In Video_TS folder I found not only .vob files but there are also some ofther files like INFO and such. I'm just guessing that they have to do with how the movie comes together. Do they store information like what size each of the large VOB files is and when it starts and finishes? If so then probably they need some editing as well. It's my first edit so all help will be most welcome.

Not a good practice to simply re-name a VOB to .mpg...Next time use something like VOB2MPG to merge to single .mpg file for editing...When done editing you can import the .mpg in a conversion app like ConvertxtoDVD, DVDflick, or similar, but it will re-encode..For no re-encoding you'll need to extract the streams from the .mpg and re-author a new DVD...

VOBs (Video Objects) are a lot more than just a MPEG. They may contain subtitles, menu information, alternate languages and other information and are part of the DVD structure, along with IFOs (Information) and BUPs (Backup) They are created by a authoring program. You can't just edit them as a MPEG and stick them back into the VIDEO_TS folder and expect the DVD to play.
For more information on the DVD structure, format and specifications, look to the upper left on this page for 'WHAT IS' DVD. As mentioned, you can extract the MPEGs from a VIDEO_TS folder with VOB2MPG, but you would have to reauthor to recreate the DVD. Some authoring programs: https://www.videohelp.com/tools/sections/authoring-dvd
Another alternative is a video editor than can edit VOBs directly. Some here: https://www.videohelp.com/tools/sections/video-editors-mpg-dvd

This all sound very complicated. Thought it would be much easier to do and there is some software that can read all the dvd and show me all the parts of it including current settings and modifying them accordingly to my changes. It's going to be a really tough one. Thanks guys for your support and all the info.

Ok so I edited that vob in Ulead Studio and then saved it. Then copied all the other VOB's from the DVD and replaced to one I was editing. Then put everything back on a new DVD. It kind of works but there are problems. For example if I go to chapter selection it skips the chapters I edited. If I go to scene selection my edited part works fine except it's under the wrong link. So it's getting wormer but not perfect yet. Any ideas how can this be fixed? Thanks

And if some of the editing included moving around chapter points, that can be done by editing the celltimes.txt file that PGCDemux gives you. There are other ways to do this but the way you did it isn't one of them.
If all you're doing is changing the music track, demux, remux with the new audio, replace. -
Hi. The only edits I did was muting some parts of audio and adding another tracks in those points. Probably like 5mins in total.
Probably this is why Ulead Studio created 2 VOBs. One around 1GB and the other quite small containing maybe 2mins of video.
Do I need to Demux all the movie or just the one vob that reqires editing?
Thanks a lot

It actually all takes place in one chapter but there are a couple of chapters in that Vob file. Ulead Studio gives me the choice to import only one chapter as it asks what chapters I want to import, but I had no idea how do I put it back after editing as it creates a vob file in the end. For that reason I worked on that whole VOB. But if as you're saying I can edit just that one chapter that's even better as it shouldn't affect all the rest that much.
Jut wandering if I add some audio there, it will probably change the size of that chapter which in turn will probably lead to a situation where it won't fit into one vob again. That's why when I was working on whole that vob file and it's vob no 3 in this case so one but last I didn't care that it cut some end of the movie from that vob and created a second small one. I just ignored that small one which contains bits I don't really care much about and only stick the main one back in the original Video_TS folder changing its name to be no. 3. I didn't have to change the extension back to vob as it came out as vob from the Ulead Studio.
I'll try your suggestions straight after getting back home. Thanks again

I do, sometimes, replace a cell with a reencoded cell and it works fine. I reencode video, though, and don't usually mess with the audio.
After you've edited the cell (I still highly recommend PGCDemux for the demuxing part), open the original unedited DVD in VobBlanker. Highlight the main video so it appears in the lower screen. Highlight it in the lower screen and hit "Cells" on the right. In the new screen the cells will be shown. Highlight yours and hit "Replace". Scroll to the VTS_01_1.VOB->Open->Apply, give it an output folder, and "Process. -
I'm a bit stuck again. After editing that one cell what do I do with it? Do I as before export it to a VOB? Will a vob file be accepted by VobBlanker as a cell? PgcDemux creates an .mpa and an .m2v file. The celltimes.txt is empty when I export one cell only. It only gives me times when I import a whole vob. So what do I do then. Ulead gives me options to export to DVD, VCD or SVCD only. I don't think any of whose gives me .m2v and .mpa as a result.
Also there is one think I don't get from your description. Why do I choose VOB_01_01 if my edited cell is in vob03?
yaro -
If editing only a cell, then the celltimes.txt file is empty, you're right. Muxman fits in by reauthoring your edited assets. Load the M2V, the audio, subs if any (in SUP format), and mux. When done you'll have a little DVD and you can then replace the original cell with your new VOB in VobBlanker.
Why do I choose VOB_01_01 if my edited cell is in vob03?
By the way, there was probably an audio delay in the original cell. "Check A/V Delay" for that cell in PGCDemux. If there is a delay, be sure and fill in that same delay when remuxing with Muxman. -
All right. Actually when I export with Ulead Studio it creates a little DVD with only that one scene. So I get Audio_TS and Video_TS folder in result. The Audio_TS is empty but the Video_TS contains all the .ifo, .bup and .vob as you would see in a normal DVD folder. So I'm guessing that's what I need. I clicked Replace, pointed to my edited vob and processing now. Can't wait to see the results. Hopefully my firs edit will be completed. That was really great help. Thanks a lot

Unfortunately it didn't work. All the edited part has no sound. Also scenes were moved from chapter to chapter. Seemed to be so close
yaro -
Does the cell VOB you created have sound? When you play it as a DVD (not just as a file), it plays OK? Is it the same kind and same bitrate audio as the rest of the DVD? It's only after you do the replace step in VobBlanker that the audio is lost?
I'm not sure what you mean by scenes were moved from chapter to chapter. If you started with only the one cell, then nothing can get moved to a different cell during or after the replace step in VobBlanker. -
dvdremakepro would be your best option for your problem. It allows you to replace blocks/cells in your already authored title set.
To keep it quick you could just replace the blocks that the last vob uses in your authored dvd with the new vob file you made from your editing
dvdremakepro also allows the splitting of chapters to make cells and so on and so forth. You can easily fix your disc using this program but you need to know a little something about the dvd structure otherwise viewing it's interface might be a little intimidating -

Anyway, Yaro's problem doesn't seem to me to be one that using DVDRemake Pro would solve. -
I checked the edited vob with VLC player and Windows Media Player and it does have the sound I want. Audio bitrate of the pieces of songs I added in to replace the old ones is probably different than the original one as I used mp3 files and I don't know what format was originally used for audio background for that DVD. After VobBlanker the audio is gone from the output. By moved scenes I mean that when I fire up whichever vob with VLC from the original movie and the VobBlanker output it starts from a different point of the movie. Same if I go to DVD menu and choose scenes.
Maybe the procedure I used is wrong so I'll try to describe step by step what I did.
First I pointed PgcDemux to my folder with the movie and to the VTS_01_0.IFO which showed me cells from 01 to 11 and exported cell number 9(02/08). This created m2v and mpa file. I opened the m2v with Ulead Studio and added my music files and the mpa file muting the bits of audio I did not like. This part was pretty stright forward as Ulead Studio is quite intuitive showing you your video, audio and voice streams one above the other so you can see exactly what you're editing.
After I finished with editing in Tools I've got Create Disk > DVD. There are options to create manu and Add/Edit chapter. I didn't won't an new menu so unticked that and went Next where I can choose to create Disk, DVD Folder or Disk Image. I went for DVD folder which created a small DVD including all the files that you would normally see on a DVD disk except there was only one vob which was my edited cell.
Next step was VobBlabker where I pointed to my original movie folder > VIDEO_TS > VIDEO_TS.IFO
I chose some output folder and clicked on my VTS_01*.VOB Then I chose PGC# 02OneSeq which by the sizeand duration looked like the main movie, clicked Cells and highlighted cell umber 8 (there were cells from 1 to 10) as it matched the duration of my PgcDemux cell. Then I clicked Replace, pointed to my edited vob and applied. Now Process!!
After it finished I had all the files which were in my original VIDEO_TS in the output folder. When checked file details all the files were slightly different to their original size except for VIDEO_TS.VOB which was exactly the same but e.g. the new VIDEO_TS.IFO was KB where the original one was 32KB. All the new VOB files were also slightly bigger where the original e.g. the original VTS_01_1.VOB was 1,000,016KB but the new one was 1,048,574KB.
That's how it looks like. I must have done something wrong but just can't see where.

Where you see the funny face there is actually 9 ( 02/08 )

I checked the edited vob with VLC player and Windows Media Player and it does have the sound I want. Audio bitrate of the pieces of songs I added in to replace the old ones is probably different than the original one as I used mp3 files and I don't know what format was originally used for audio background for that DVD.
There are other ways to check the audio. I use HeadAC3he often. GSpot and MediaInfo will also tell you.
I expect the moving scene thing is related to you using the wrong audio for the replacement. Get that fixed first and then try again. You didn't think it would be this hard or time consuming, did you? -

yaro -
It's actually 224 not 222. So I resampled my MP3s and trying again. Thing is the size of the original audio stream is 170MB and the new one only 10MB. Would this matter?
