Re-join single DVD-9 film split onto two DVD-Rs

[denti alligator]

I have been using DVD Decrypter and IFO Edit to split films on one DVD-9 onto two single-layered DVD-Rs so as not to compress the film in any way. Each disc keeps the original menu, some of the extras end up on one disc, some on the other. How can I join the main files for the film into one again, keeping the menu(s) so that I can watch everything from my HD? Understand that the files that have been split constitute one film, and I simply want to restore that film to one set of VOB files.

Essentially, I want to reverse this process:

Why not just re-rip the original?

The easiest way is probably by using DVDRemake Pro, although it costs money:

A: Rip both to seperate folders on hard drive .
B: Launch pgcedit , open the one containing the menus and extras .
C: Now import vst title (main movie) , from the other rip folder (choose copy)
D: Fix up nav commands required for main movie reintergration , as the vst title number may have shifted from original position (dont forget , buttons have nav commands as well) .

Its handy if you had exported all the nav commands from the original dvd via pgcedit , and kept it as a reference backup for such a process .

E: Save dvd , play back on pc using more than one playback product to ensure its working correctly , then burn to dvd .

Simple when you know how .

So I tried following the directions in this thread, renaming the second half of the VOBs following after the first half and it doesn't work. The film stops at the end of the first half and doesn't recognize the second half. How do I actually join these two segments after having renamed the VOB files?

If you're talking about my contribution to the thread to which Baldrick linked - about renumbering the vobs - well, that was for someone that was going to reencode for a DVD5. If you just renumbered and then stuck them all into the DVD with the menus, then of course it won't work. You'll have to mess with the NAV commands, as Bjs suggested.

Can you elaborate on this step. I'm not sure how to do it.

C: Now import vst title (main movie) , from the other rip folder (choose copy)

When I do this I get the following warning:

"New VTS 7 (1 title) imported OK

Import the 3 TTN VOB files (2.07 GB)?

WARNING: There are already some VTS 7 IFO/VOB files in your DVD folder.
IF YOU CONTINUE, THEY WILL BE DELETED FIRST."

When I choose "copy VOB(s)" as you suggest, the program crashes.

I just chose "move VOB(s)" and now it seems to be fine, but how do I get these VTS 7 files together with the VTS 2 files (where the main movie is)?

[denti alligator]

Never mind that error message, that was because those files had been copied before the program crashed the first time I tried.

So they're there as VTS 7 and I need these to be seemlessly integrated with VTS 2. How?
