As far as I understand the matter of direct stream copy of audio
it is only possible by reading the audio by another codec.
As the standard codecs decode both video and audio.
Right?

OK, as mostly I only change visible effects in the video
(no fps change etc.) my typical work flow is to use
"direct stream copy" with "from another file".
This works well for MP4(AVC,AAC), by reading the audio
with the "Quick Time decoder".
But - as I now discovered - fails for WMV9 (even if both
audio/ video are CBR), reading the file with the WMV plugin (by fccHandler).
The audio is out of sync (too late).

What did I do wrong?
