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. http://www.amtechdisc.com/dvdspecs.htm 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 :) > > Otherwise, maybe pioneer would licence thier linux version of the > > MLP tools. > > If that's what they are using in the standalone recorder.

Meridian aren't very forthcoming about thier licencing terms, but thats how dolby do thier licencing. - Steve
