authoring DVD-Audio or audio-only DVD-Video from 44.1 audio data

I have some aiff files that are too big for a cd-r but would fit on a
dvd-r. They're standard cd audio format: 44.1Khz 16-bit pcm. Can I
create either a DVD-Audio or audio-only DVD-Video image with this data,
_without_ resampling? What software would I need to do this? I own
Toast 6, iLife 5 and ffmpegx, but I'm not clear that any of these tools
can do this. I'm happy to build and use opensource unix/linux apps if
that's a viable alternative. I'm also willing to upgrade to the latest
Toast and/or iLife, if that would help. I'm probably not willing to
spend a lot of money on professional software, though, at least not
right now.

If resampling is a requirement (eg if for some reason dvd audio has to
be 48K rather than 44.1), what osx utility does the best job?

TIA.

 

Following up my own post here --

Thus turns out to be very easy, and I apologize for having posted the
question before I did enough research. For anyone else who might be
interested:

1. Download the sources from http://dvd-audio.sourceforge.net/alpha

2. Build the sources (unzip, cd to the src directory, type 'make')

3. Run the following command in Terminal:

dvda-author -o MyDVD -g mydata.wav

where MyDVD is the name of a new directory where the data will be
written, and mydata.wav is the name of the audio file. You can include
multiple -g values.


A minute later, the program will have created the new directory with an
empty VIDEO_TS and suitably formatted data in the AUDIO_TS. It's a very
fast process. This directory can now be burned to dvd-r as a udf image
with Toast, resulting in a properly authored DVD-Audio disc that should
play in any DVD-Audio player (though I can't verify this until my player
arrives next week).

No resampling is necessary: the DVD-Audio standard includes support for
44.1/16 data and dvda-author handles it without issue.

The only small downside with dvda-author is that it only accepts wav
(and flac), whereas my files are aiff. But aiff->wav is a quick
lossless conversion I can do easily with Quicktime Pro.
