Itay Roussono audio through digital output
by on Nov 23, 2004 at 6:32:57 am

Hi,
I've authored a DVD from my camcorder, and everything was fine. I used the audio file generated from the encoding process - which is *.mpa format and did not choose to transcode it. When I played the DVD in my player - I could only hear the audio through the analog output. If I had my optical fiber connected - no audio was heard.
Does anyone know what I am doing wrong here?
Thanks,
Itay

A set top DVD player won't send .mpa (MPEG-1 Layer II) audio to the digital output. Many NTSC players don't support MPEG-1 Layer II audio at all. Just let Encore convert the audio to Dolby Digital (AC3).

just another quick question... :)
If I will let Encore encode my audio - would you recommend to use the mpa (which is already compressed) file or perhaps I should encode the original wav file? This will not cause sync problems correct?

If you got an uncompressed PCM (.wav) file, by all means use it! As you already suspected going from one compressed format to another compressed format is not the preferred route. If audio and video don't already have sync problems, the conversion to Dolby Digital (AC3) shouldn't introduce any new ones either.
