How do I write new subtitles to a DVD (by listening!)

[cemman]

Hi, I tried to find an answer in the forum but I couldn't, so if there is one I apologize for my incompetent search skills. Now, I have an original DVD which doesn't even have a closed caption. So I needed to write one my self. Luckily and strangely enough I found one in Dutch! So I had decent time code as far as the first part of the movie.VOB file goes.
So I started to translate with Subtitle Workshop. Since I don't speak the Dutch I started listen to the movie and change the sub accordingly. It was all good until the first VOB was ended. Obviously I was set to be punked when I loaded the second VOB. The time code wasn't continuing from where the first VOB left out! (Daa.. ) So I don't know which line is that I am editing now!
(I am sorry this is so long :=)

Now what am I suppose to do?
A) Am I to convert all the VOB files to one AVI, so that I can load it to Subtitle Workshop and sail away? How do I do that and should I worry about the possible sync problems?
I mean when I finish the sub and mux it back to DVD, will it be in the same time-frame zone as it's AVI counterpart?

Or B) Is there any other way to pull -this task- off without hurting myself?
Thanks a bunch before hand.

Use a smaller font for yor next post. It's hard to read...
If your vob files are from one continuous movie, you can join them with a simple DOS command:
copy /b VTS_01_1.VOB + VTS_01_2.VOB + VTS_01_3.VOB fullmovie.vob

cemman,
You can also join VOBs with VOB2MPG and load that file into Subtitle Workshop.
Womble MPEG Video Wizard is great to open VOBs and join them to a single mpg file.
There are other ways as dicussed here:
