Would the .vob files stay exactly the same?

My friend has an audience shot concert DVD (PAL) that I'm supposed to get in the next 2 days. He wants to make a menu and upload it on a tracker, but he's having trouble with TMPGEnc and other DVD authoring programs (unspecified errors).

Two things I want to try:

Just simply put on a menu with TMPGEnc and hope that I don't get errors. Will changing the menu change the .vob files in any way? He also wants to help seed the DVD and it won't work if they are different.

If I do get errors, I want to use VOB2MPG and use the output mpg file with TMPGEnc. Will that change the VOB files?

The best option might be to extract the MPEG file from the DVD with VOB2MPG and re-author it that way. That should avoid the TDA problems. Then you should have no problems with making new menus. VOBs contain MPEG-2 video, subtitles, audio and alternate audio tracks and menus. See 'WHAT IS' DVD to the upper left on this page for the DVD structure, etc.

If the VOBs are damaged, you may be able to repair them. Maybe IFOedit or similar.

You mention it's in PAL format. Do you plan to change that to NTSC? There's quite a bit of work involved and it is fairly difficult. Not really recommended unless you have to.

Or you could just convert the whole thing to Xvid/Divx. It would make the file much smaller and faster for downloads.

If you change the menus, you will change the vobs and therefore probablu cause seeding problems. You will most likely have to create a new seed for this version.

Oh ok, thanks. So I'm gonna have to mail my friend the fixed version and he's gonna start seeding. I might come back here if I run into a wall in fixing the DVD. :P

By the way, does anyone know why a 62 minute DVD would show up as 11 hours on TMPGEnc, or go out of sync on AutoGK? It's in PAL, is that the reason? If it is, is there any PAL-specific authoring program/converter I could use? I don't feel like converting to NTSC to be honest.
