DVDLab audio rejected

[SaSi]

I have a problem with some MPEG streams I feed to DVDLab. All my assets are prepared with Mainconcept using the same template. I encode to separate audio and video streams with audio MPEG 192kbps.

Practically, half the audio streams cause problems with DVDLab. It doesn't explicitly reject them, but it will either crash during compilation or compilation will succeed but the video will playback in "slow motion" with audio in normal speed, audio will run out and video will continue silent at normal speed.

Needless to say the streams are perfectly valid and Scenarist accepts them without any complaint and compiles perfectly playable DVDs.

Has anyone seen this behaviour?

Mixed audio files!?...

I too had problems with DVD-Lab and mpeg audio. It would import and compile OK but it wouldn't play OK. Other authoring tools had no problems with the same audio streams. I couldn't figure out why (probably a bug with DVD-Lab) but I found a workaround:
Import the mpeg audio at 44.1kHz. It will complain (obviously) and offer you to convert to 48kHz with its own audio transcoding tool. These worked OK each time.
Slight quality loss if your original was already at 48kHz though.

Sounds like the workaround I found myself. I now got an even worse case where the DVDLab transcoder won't even transcode the file. Thankfully, it was able to convert it to WAV which I then re-encoded separatelly with MainConcept. The new MPEG audio file was properly accepted and compiled without any problems.

Likely to be a bug in the s/w. Let's hope it will be fixed in the final release.
