Chapter problems when turning a 2 disk movie into 1 disk.

[mattstan]

Hi,

I've a chapter points and timing problem when ripping a 2 disk movie to burn onto 1 disk after shrinking. The chapters and time is not correct.

Here's what I did...

1. Rip both DVD's main title.

2. Use DVD Shrink in 're author' mode, add both 'main titles', get rid of unwanted audio and subpictures, and shrink to fit on 1 DVD.

3. This results in an ISO file, containing the 2 titles, ready to burn.

All well and good -- this works fine but as an experiment I wanted to try to merge these 2 titles into 1 title. Here's how:

1. Use WinRAR to extract the files from the ISO file DVD Shrink created.

2. Use VOB Edit to change the VOB-ID of the 2nd title VOBs so that the ID's follow on from title 1 to title 2 in the correct sequence, so if the last VOB-ID of title 1 is 3, the first of title 2 is 4. VOB Edit creates the new '2nd title' VOB files accordingly. Rename the newly created VOB files so that their sequence is correct and matches title 1's VOB file sequence. EG. Title 1 VOB files are: VTS_01_1.VOB, VTS_01_2.VOB, VTS_01_3.VOB, so the newly created 'title 2' VOB files are renamed: VTS_01_4.VOB, VTS_01_5.VOB, VTS_01_6.VOB.

3. Get rid of the old IFO files and their BUPs and use IFO Edit to completely re-create the IFO files.

4. Use IFO Edit to specify the audio and subpicture streams in the IFO files.

5. Finally use IFO Edit's 'Get VTS Sectors' on all (there are only 2) the ISO files.

6. BURN to DVD.

Now what happens is: what was 'title 1' plays perfectly, chapters and the time are all correct. When you get to the bit in the movie where 'title 2' would have started (if there were 2 titles which there aren't anymore just the 1) the time resets to 0 and the chapter resets to 1. Worse if you skip to the next chapter the whole film restarts from the very beginning!

What did I do wrong? How do I achieve what I wanted to which was to turn the 2 titles of half a movie each into 1 title of the whole movie with working chapters! NOTE: I'm not worried about keeping the original chapter points, in fact I'd quite like to replace them with chapter points every 5 mins but again I'm not worried about achieving this, just getting them working with the least effort.

Also when I examine VTS_01_0.IFO to see the chapter points, the first 36 chapters seem normal (this corresponds with 'title 1'), then follows 33 chapter points which each last exactly 12 frames! After that the chapter points seem about right again and throughout the chapter number sequence is correct 1,2,3...98.

Any ideas what I must do to sort all this out?

Thanks,

That seems like alot of work. What is the purpose of making 1 title? If that was totally necessary, I would use TMPGEnc DVD Author, put the 2 'tracks' on 1 'title' and insert auto chapters @ the 5 min marks.

You're right it was a lot of work but mainly in processing time which was all done as a background task. I was doing it all in part as a learning exercise, I'm still quite new to all this.

Thanks for the DVD Author suggestion.

I think the problem is with IFO Edit. If you have PowerDVD you can check it by opening the IFO files in the folder to simulate what your burnt DVD situation.

Strangely, the DVD Shrink would scan the VOB in sequence you set on VOB, and even shrink the VOBs accordingly. But the IFO files created still screwed up the sequence.

Am in process to investigate the problem to see anyway to correct the problem. Should anyne know, I'd appreciate to know.
