DVD Architect - Problem - VOB file

[Cunhambebe]

It's been a while since my last post, so first of all, I'd like to say HI!
Now let's get to the point: I've got a VOB file around here (only one file), about 3,9 BG. I've demuxed its audio as AC-3 with the help of TMPGENC. Everything seemed perfect, but as soon as I opened the VOB file with DVDA, the timeline showed a smaller size for the video (although I've checked the file and it was totally complete), while the audio was much bigger. Previewing the file at the very beginning doesn't show any sync problem. I was just wondering what the problem might be since I've already used this method for smaller VOB files (about 48 minutes - don't know the size, but that must be much smaller than 3,9 GB). It seems DVD Architect refuses to open the whole file, but just a part of it, instead.
Help will be greatly appreciated..

there is a segment end code in the header - the vob must of been made up of smaller sections ..\\\try running the mpeg file through restream and select remove seq. end codes and reset time stamps

you can pretty much also do it using pulldown.exe and dont do a pulldown, just parse the file and resave..

i bet mpeg2vcr will also fix it ..

Hi there!
Thanks for taking time to respond - as always. Pulldown.exe seems not to work here, as I click on the .exe file a DOS-like screen pops up and that's all (forgive my stupidity, I've just downloaded PulldownBatchFE). By the way, Is there any way to do that with DVD Decrypt???
Thanks in advance.

DVD Decrypt

not sure- maybe if you save the whole DVD as a m2v file ..... but then you will have to multiplex it up again ..

pulldown and restream should work -- restream especially ..

if you want to make a dvd with your vob load it in to grab&burn 3 2 0 it will make the dvd in about 30 mins no menu it will set a chapter point for each vob file great for music dvds one vob/song=one chapter point even dts audio

that was not his question - on how,...

Thanks to all who took time to respond. In fact, Pulldown seems not to work with VOB files, but m2v and mpeg ones (if I'm wrong, please let me know).

-In fact, I wanna run the VOB file itself (can I just rename its extension as MPEG?)

BJ_M wrote: pulldown and restream should work -- restream especially ..Can I ask you how???????

By the way, this is very curious because about a month ago I insist: I loaded a VOB file (about 48 miutes) in DVD Architect. No demux, nothing, just had to drop the VOB file there and demux (yes, this time) the audio with TMPGEC as AC-3. Now, I realize this method is not working out properly for bigger VOB files like the one I'm trying to drop in DVD Architec (3.9 GB). I do agree with BJ_M on end codes and everything else, but the thing is: I wouldn't like to demux the VOB file as m2v or MPEG because there may be a loss of quality (am I right here?).
Just in time: demuxing the VOB as m2v with TMPGENC seems to fix this and the m2v file can be dropped with no problems at all in DVD Architect (no need of Pulldown or whatever). Would there be a loss of quality? How about just renaming the extension as .mpeg or m2v????? Now I'm gonna try Restream and reply with the results a little later...
Thanks in advance.

[BJ_M]

no loss of quality in demux, its exactly the same file ..

using a vob as program stream is taking your chances - a vob can contain many things ..

better is to demux to m2v and remux to program stream with tmpgenc with no audio ..

i thought DVDA required a program stream ? (i dont use DVDA myself) - if not , do as you said above...

time consuming though -- hence the much (usually) easier drop the vob in DVDA (which by the way will demux and remux it anyway in a way)

[BJ_M]

if you DO demux as you said -- you shouldnt need to run anything through restream -- as you would have prob fixed the problem at that point anyway ..

I've had this exact same problem, and seemed to solve it be letting ifoEdit recreate the VOB file information, and write new files

That has also cured some strange problems that TMPGenc DVD Author struggles to load some DVD VOB files, and also takes an absolute age to recognise the VOB

Running it through ifoedit and either backup or simply overwrite the originals with the new ones created by ifoedit cured all the problems

Just run ifoedit and choose 'create new ifos' and follow the instructions, shouldn't take more than 5 minutes maximum, but make sure you move the progress bar off screen as otherwise it will really slow down, strange but true

ver 1 of DVDA required a program stream, v2 now allows use of individual video and audio streams

@Cunhambebe - fwiw, I think I had something similar to the above...did you try to open the VBO in mpeg video wizard (or mpegvcr) and just write the whole thing out as an mpeg file (e.g. don't cut it but just let the tool write it out for you as one clean file)?

also, if you are stuck on this one part and download the demo of dvd-lab (www.mediachance.com - try the regular version - don't need the pro version), you can open the vob file and dvd-lab will demux it for you [... the nice thing about this is if you have several smaller files, it will combine the mpegs into one long mpeg]

good luck!

Thanks again to all who took time to respond!

Sorry, but I guess I've been misundestood. This is what I've been trying to do with no results at all = I'VE BEEN TRYING TO DROP VOB FILES IN DVDA. As I've said before, this method (just dropping the VOB in DVDA) DOES WORK ONLY for SMALLER FILES (not for a 3.9 GB). Why? Because just half of the file ( the one this size) is opened. Again, as I've said before, I would try to rename the .VOB extension as MPEG or m2v. The result? Same thing = DVDA accepts the file but just half of the file is opened.

Sorry again, but I guess (if I understood your statement) restream and pulldown only accept m2v and MPEG files. VOB cannot be dropped there!
Anyway, thanks for letting me know a bit more about demuxing....AND YES, I'VE ALREADY FIXED THE PROBLEM.
-no loss of quality in demux, its exactly the same file ..

Thanks for the input on ifoEdit, but I guess this way, with one more prog, I'd better write a thesis or something.....I just want to make things more simple..thanks anyway, fella!

No, I didn't. No need to do that. Thanks for the info on dvd-lab.

So, finally, do u all wanna know the result? I demuxed the VOB file with the excellent TMPGENC (no loss of quality at all). DVDA accepted the m2v file, I inserted my new subtiles and re-authored my DVD

Just one thing: I STILL DON'T UNDERSTAND WHY DVDA DOES NOT ACCEPT BIGGER VOB FILES (JUST OPENS HALF OF THESE FILES). THE PROBLEM MUST BE THE HEADERS OR SOMETHING AS BJ_M HAS CLEVERLY POINTED OUT.

THANKS TO ALL!
