problem mit ac3 stream beim muxen

[vulgo]

hallo!

ich hab hier einen ac3 stream der beim muxxen nicht mehr 'weitergeht' allerdings tut er das doch. höre ich ihn mir zb mit dem vlc player an, dann merke ich gar nichts von einer lücke.

beim muxen allerdings ist die ac3spur ab einer bestimmten zeit ohne ton
zum demuxen verwende ich pvastrumento zum schneiden mpeg2schnitt oder cuttermaran (geht mit beiden nicht) und zum muxen enweder die internene muxer oder imagompegmuxer.

geht leider mit allen drei nicht ABER ich hoffe es gibt irgendwo eine einstellung mit der ich das behen kann, die ihr kennt

beim ac3 handelt es sich übrigens nicht um dolby s. 2.0 sondern um DD 5.1 (die bezeichnung ist nur falsch-warum auch immer)
