Yep, DVD-video and DVD-audio are two different beasts.
The DVD-A format by itself doesn't look bad, and it supports
uncoded multi-channel sound at high quality. Both the DRM and
the MLP coding are optional, so in theory you could create
DVD-A disks using only open source software. The matter was
discussed some time ago on the surround sound list, as the
DVD-A format is the only 'mainstream' one allowing musicians
and composers to create their own multichannel recordings.
But real full-spec DVD-A players are rare, and the future
of the format isn't very clear.
