how to add 6 PCM tracks to a video DVD

Hello!

is it possible to add 6 audio tracks (48khz/20bit) to a DVD? i am using
DVD Studio Pro and i can only add one stereo PCM file to an audio-track.
when i am using "A.Pack" this works but then the audio is AC-3 encoded
and has not PCM "quality".

any suggestions?

cheers
markus

It can't be done as it exceeds the bandwidth of the format. If you want
6 channels then you must use Dolby Digital via APack. Don't use the
defaults though. Use these settings and it should sound better:

Data Rate: 448kbs
No Compression
Dialnorm: -31
RF Modulation - Off

I want to have six channels for Dolby 5.1

I believe Linear PCM only supports stereo, although I could be mistaken.

A utility like A.Pack can create a 5.1 soundtrack from separate audio
files, whether stereo or mono. The thing is, you need to have recorded
and/or mixed your audio to take advantage of 5.1 -- you can't just take
a stereo track and magically make it 5.1.

I have read in dvd studio pro manual that the max data date is 6144 bps -- if
i use a very low video quality ,or say i take a black picture, is that still
insufficient?

PCM tracks are limited to either mono or stereo.

The only way you could have 6 different PCM tracks would be to put
them on as different language tracks, and there would be no way to
play them simultaneously for a full-mix.

You need to use Dolby Digital or DTS - they're the only formats that
can output 6 discreet channels.
