1.0.6b4: mp2 audio is just plain silence

[oliv]

Hi there.

After 10 successfull SVCDs, I have some problems with 1.0.6b4.
My .mp2 file is there, but I can only hear silence when I play it through wmp.
I never had this before.
The logs are following.
Just one clue about this: the .ac3 audio is there and OK (I can play it through powerDVD).
A problem with besweet ?
Any help is greatly appreciated :)

Thanks...

-g 0 will create plain silence ;)
you should use -g 0db , or even better -g max .

Hi DSPGuru.
Never better served than by the master himself :D
Thanks for this answer.
So, I guess I had that because in the ' Audio' tab of DVD2SVCD, the 'Azid Gain offset' was set to 0, as you can see here:
http://famillejacques.free.fr/dvd2svcd.jpg
Don't know how I got that though.

Anyway, thanks a lot !
(and the BeSweet tool is something I just love ;) )
