Hello Richard,
I can do that, but for now it seems that i have the problem solved !
I duplicated the folder with all the *.MST files and changed the extension in *.M2TS and imported
all the clips again through media browser in *.M2TS format and now the audio is just perfect !
Do you know why it works with the M2TS extension ? Does it matter for the quality if i change the extension ?
Thanks for your attention ;-)
Greetz,
Mark
