Sounds silly, but I have no idea, never tried video or even looked at
it :) The software (http://www.minnetonkaaudio.com) is audio-specific.
Just to be clear, we own an internal DVD-R/RW Pioneer drive (sub $300),
not the stand-alone Pioneer setup Daniel was referring to. The
multi-channel mix (the music) is encoded in software to an mlp, and
then burned with DVD-A authoring software.

Anyone else have more information about this? Is there another way to
handle high-resolution DVD-A?

I'd be interested in having another look at this question. What can we
do today with Linux for DVD Audio? Frankly, I remember being
disappointed with Audio capabilities under the Video specs, which is
why we spent the cash and bought the mlp stuff.
How far (sampling/bit) does 9+ MB/s get us with, for example, 4
channels of audio (too lazy to do the math -- it's 5 am)?
