Hi,
I've finally tracked down this audio bug. Turns out it's not in
mythtranscode, but in libmythtv, the NuppelVideoPlayer::AddAudioData function,
which leads to the problem for mythtranscode and nuvexport.
Now I can finally and perfectly export my recordings :>
The patch is against 0.14 release tarball, it's simple enough:
