I have created AC3 and DTS audio tracks from .wav files.
To AC3 I have used ffmpeg v03. When I have imported audio which I have created into Maestro I have got a warning - wrong framerate, but multuplexing continiues...
I have check framerate using delaycut and I saw that framerate is about 32Hz. I require 25Hz.
Is any possibility to set manually required framerate before starting wav to ac3 conversion? In ffmpeg. Or maybe there is another tool which is better than ffpeg?
The same problem I have got using DTS track which I have created using SUR CODE DVD DTS - the framerate is about 100Hz???? (10ms frame period). In this case I have the same questions as above... But sitiuation is even worse, because multiplexing in Maestro doesn't start with this DTS audio...
Any suggestions????

For my first question I have found answer by myself...
Finally I have resigned with GUI to ffmpeg and at command prompt I started ffmpeg as follow:

ffmpeg -i input.wav -f ac3 -ab 384 -r 25 -ac 2 -ar 48000 output.ac3

it gives me what I want - AC3 with 25fps framerate... I hope so...
But Maestro doesn't show any warning about illegal audio fps anymore.
That I thik it helps...

WHAT ABOUT DTS???? Anybody...

Um...I'm no Maestro expert, but audio doesn't have a framerate. Video does.

You might be better off going to the DVD Authoring forum over here. Do a search, first, and see if your question can be answered. I'm doing a LOT with both AC3 and dts (primarily dts) in Maestro right now and have never gotten that warning.

Maestro has refused to compile before and gave me an INVALID FRAMERATE message, but this was cured by setting my P4 processer affinity to 1. I don't think that this was your problem, though...

Did you try checking the box to ignore embedded AC3 timestamp? Why are you 25 fps? Is this PAL?
