Revised: I have now found out something about the difference between MPEG2 and Meridian Lossless Packing.  I am doing a DVD with  96k/24bit audio and want that to be preserved on the DVD.  There will be two hours of video.  How can I best encode two hours of 96k/24 bit.  It is just in stereo and not surround.  And will I need a Dolby track (even tho' I don't want one)?

Thanks!

You can't author a DVD-V with MLP nor a DVD-A with Video.

But...

Your bandwidth requirement for stereo 96/24 PCM is 4.608 Mb/sec, and the available bandwidth for audio is 6.144 Mb/sec, so at least on paper you're good with a little headroom for the AC-3 stream and then some for the video. Running time will be short, though.

However...

With a very good authoring on DTS you can get away with a lower bitrate, multichannel, and good video.

Thanks Carlos!

Video is going to be the "star" of the DVD.  I just want the best possible audio.  The running time will need to be about two hours.  What do you suppose will be the format for the best possible audio quality?  I don't really care if an AC3 stream is on the disc.

The best possible without sacrifying video quality is DTS at 1536 kb/s. You can still leave an AC-3 running at the bare minimum of 64 kbps just to get it going in computers and old devices, since the DVD spec sets as mandatory to have at least either AC-3 or PCM.

Thank you Carlos for the information and the link.
