24 bit audio comes out as 16 bit... Why?

I try to make DVD-V discs with still pictures as Video content and 24/96 Linear PCM as Audio. I add 24 bit audio files, but the resulting audio on the disc is 16 bit (96k)... Why is that so?

Vegas is supposed to passthrough PCM 24/96 stereo, perhaps you need 1.0c, or just a newer DVDA than you've got.

I think the expectation is that the PCM 24/96 2.0 is in a WAV, and not an AVI or an MPEG-2 program stream. Not sure on that last bit, but you could compare which works.

The other part that might affect the number of bits could be identified if you look in the Optimize DVD dialogue in DVDA. If it says it will recompress render though then I'd have expected 16/48 for LPCM.

What source is the LPCM, I mean which app rendered it and with what non-codec settings?

If you don't mind answering all the above questions, could you also confirm the video was compliant when it arrived in DVDA please?

It is DVDA 1.0c.

The audio is inserted as a separate wav file (24/96), in Music compliations or with "Insert Media". These files are created with Samplitude. Files created with Cool 1.3 cause the same result. Do I *need* to use Vegas files...?? I prefer other software for audio.

The Optimize-dialog says nothing about recompression.

"Video" was ok, although it was just a still picture or even nothing (black screen).
