Essentially, I want to be able to take the files, rebundle them into a DVD structure without editing the individual streams and have a simple menu structure to access them; the problem I seem to be hitting is that the proprietary stuff I have won't accept a VOB file as an input, or will try to transcode the things to suit itself (and since the video quality isn't exactly great in encoder terms, I'd prefer it left it untouched!).

You might want to learn a bit more about how DVDs work. Try my web site at:
http://dvd.sourceforge.net/dvdinfo/
I created that site while coding the DVD support in xine.
>From the old DVD, you will have the menu .ifo and .vob files. called
Video_ts.ifo (The index, used for menu navigation)
Video_ts.vob (The video and menu highlights for animated menus etc.)
Video_ts.bup (A duplicate copt of the .IFO file)
The old DVD will also probably have a single title called:
VTS_01_0.IFO (the index, used for fast forward/rewind etc.)
VTS_01_0.VOB (The video)
VTS_01_0.BUP (A duplicate copy of the .IFO file)
What you need to do is take the VTS files from each DVD, and rename them so:
First DVD:
VTS_01_0.IFO -> VTS_01_0.IFO
VTS_01_0.VOB -> VTS_01_0.VOB
VTS_01_0.BUP -> VTS_01_0.BUP
Second DVD:
VTS_01_0.IFO -> VTS_02_0.IFO
VTS_01_0.VOB -> VTS_02_0.VOB
VTS_01_0.BUP -> VTS_02_0.BUP
etc.
If any video bit is > 1Gig, you have to break it into bits in a special way.
Then, all that remains is to build the menu bits, i.e. Create a new:
Video_ts.ifo
Video_ts.vob
Video_ts.bup
You can use open source DVD tools like dvdauthor for this task.
Once you have done that, you can use xine to test that all the menus,
jumping to each title works.
Once you have that tested, you can use a dvdrwtools to create a .ISO
in "dvd-video" format, that can then be written to a DVD.
No trans-coding should be needed.
