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.
