The dvd authoring tool /should/ not care what data you give it.
I like `dvdauthor` but takes some learning writing its XML format;
the `devede` GUI can create them for you.

ffmpeg can encode ac3/dts - well, check
   `ffmpeg -formats` and `ffmpeg -codecs` on your box.
ffmpeg versions differ greatly.

You do realize that you can also just use raw PCM for audio on DVDs:
48 kHz or 96 kHz, 16 or 24 bit, 2-6 channels; but only up to 6144 kbit/s

oh, you did realize :)

stereo PCM: yes. 5chan: no

I use 'ogle' http://www.dtek.chalmers.se/groups/dvd/ to test DVD iso
images. It does not use any big frameworks like ffmpeg or gstreamer for
the decoding and besides supporting DVD-menus it usually only plays what
will also play on a hardware DVD player.
