All commercial DVD-A disc releases have back-compatibility with Dolby Digital or/and DTS. AFAIK, it's part of the DVD-A spec.

Perhaps a DVD-Audio disc WOULD be a good idea, as long as it also had DVD-Video compatibility, accompanied by Dolby Digital and DTS soundtracks.
An early example of a disc like this is Fleetwood Mac "Rumours".

So this has DVD-Audio Meridian lossless (MLP) multichannel and stereo audio within the TS_AUDIO File Structure and then "normal" DVD video data within the TS_VIDEO file structure, enabling DVD-Audio players to play the audiophile music, but people with ordinary DVD players could play the normal DVD section with Dolby/DTS.
I'm assuming (perhaps wrongly) that it is necessary to explain in this detail to Ivan.

Surely releasing anything on two different systems is both expensive and commercially suicide for a new/small outfit to do.
You missed out the importance of the MLP stream on DVD-A. It's lossless and as good as Blu-Ray with the added benefit that it would be a lot cheaper to do than two separate discs.
I am sure that no-one on the surround group is a particular fan of AC3, but the question is surely one of compatibility for commercial reasons.
Not wanting to argue semantics, I am under the impression that Ivan wants a "real world" commercial answer to which is the best format in which to distribute his music, and I am attempting to provide him with a reasoned answer with which he can progress.
Just about every DVD being produced today has a multichannel Dolby (AC3) soundtrack, sometimes in addition to a 768kbps DTS soundtrack, but it is not "modern"?
Some early Universal DVDs were DTS only but they soon stopped manufacturing these discs, and adopted the approach of solely Dolby Digital or Dolby Digital/or DTS on the same disc.
Blu-ray offer better quality multichannel audio via PCM. Dolby TRUEHD or DTS-HD MA, but not everyone has a Blu-ray player. DVD is the predominant format.
Ideally Ivan, the most satisfying answer is probably to provide BOTH DVD and Blu-ray versions, as Blu-ray is best, but not everyone can play Blu-ray.

Bob, although not completely, we also commented to the subject ;-)
On your post I want to add that the topic is "modern" surround formats and AC3 is IMHO not an example of a modern format ;-)
