Thanks manolito for the German translation and extensive testing. PAL<->NTSC conversions are a nightmare for many reasons, chapters affaire is just the top of the iceberg...
Now I just have to find a couple of hours to go thru your investigations and solve all (?) the possible fps conversion scenarios within the new OGG chapters import routine.
About the Peak Level Check feature, I agree with you that it would better trigger the AmplifyDB() instead of Normalize(). There is also the possibility to move that routine directly in the AviSynth tab > Audio > Amplify Audio option, as preliminary prompt to the user.
Bye
