I was thinking more of things that are supported now. I guess you could do
a DVD-Video stream with no video (or a black screen or whatever) I suspect
most DVD-A players would play that without thinking about it, but it
wouldn't be a true DVD-A - why they are different is a complete mystery to
me.
Ahh... acording to a DVD pressing house website I just read you can store
uncomressed PCM on DVD-A discs, you still only get 9.6 Mb/s, but that just
gives you enough bandwidth for 4 24/96 or 6 24/48 channels.

Still, it could be worse, they could be using the microsoft audio format -
we'd have a fat chance of getting a licence out of microsoft for anything
:)
I'm sure Pioneer have to pay Meridian a per product cut (not much, a few
tens of dollars maybe) as it is. Meridian aren't very forthcoming about
thier licencing terms, but thats how dolby do thier licencing.

Yes, thats
very true. Are any other formats allowed for DVD-A? The
audio part of DVD video can use MPEG streams IIRC, and we have
free-ish MPEG encoders. 9+ MB/s of 4 channel MPEG would be pretty
high quality.
Ogg Flac maybe? I guess in the future there will be very few pure
hardware players - they will all be running some sort of upgradable
software. So there'll be more scope for new formats. You could burn
any format you wanted to a data DVD-R and include player software on
the disc too. Otherwise,
maybe pioneer would licence thier linux version of the
MLP tools.
If that's what they are using in the standalone recorder. If that was
the case, I expect Meridian might object unless they get a
substantial cut.
