How to author a commercial DVD

[Metallo]

Hi,

I have a commercial DVD5 and I want to achieve the following:

1) Substitute a language with another one
2) Change the menu accordingly

The DVD is in NTSC, the new language I want to add comes out of a PAL DVD.

I was thinking to demux, change the old audio with the new one and remux the whole thing.
But I think I probably need to sync the new audio given it is PAL to NTSC?
Then, how can I edit the text in the "settings" menu so that I see language ABC instead of the existing DEF ?

Thank you for your help!

Afraid not. I always convert the video from PAL to NTSC at the same time as the audio so have never had that problem.

You might want to change the title of this thread to "How to add PAL audio to NTSC DVD" or something? You might get more replies that way.

Both audio tracks should have the same length - there is no such thing like "NTSC/PAL audio".

You can use DVD Remake or demux (ProjectX) and remux (Muxman).

The audio from a PAL DVD almost certainly will not synch up with the NTSC DVD as you have 2 different framerates involved. PAL is 25fps and the NTSC, if film, will be slower and longer because the corresponding NTSC DVD will be at 23.976fps. Unless the PAL DVD was created by a funky conversion from NTSC. You've never heard of the notorious "PAL speedup" where PAL audio is speeded up and higher pitched?

Anyway, assuming the PAL length to be shorter, but that it contains the exact same amount of video (same scenes, logos, etc), I usually convert first to WAV audio using the 25->23.976fps preset in BeSweet. Then I reencode the WAV audio to AC3. And since so much can go wrong here, this may be a more difficult project than figured.

Then, as noemi7 says, after demuxing (PGCDemux) and replacing the original audio with the new one, remux (Muxman), and replace in the original DVD, getting back the menus and extras (VobBlanker). Again though Metallo, unless you've had video editing experience before, you're biting off more than you can chew here.
