Strange audio problem with Harry Potter 2 in Masetro. structure, problem, shorter, placed

andy

Hi.

Successfully authoured this movie, but when demuxxing ended up with 2 ac3 files.  One for the main movie and 1 for the extras (2 trailers).

As I am not expereinced with this sort of structure I placed the main movie audio ac3 onto the first audio track in Maestro and the shorter ac3 for the extras onto the audio track underneath (track 2) and dragged it all the way along until it lined up with the start of the extras, which were on the end of the m2v containing the main movie.  I did this as I was unable to place the second ac3 onto the same track.  Hope this makes sense.

Now the dvd plays fine and all is in synch but when I play the extras there is no audio unless I change the audio track in my dvd player.  So what I wanted was to know how to get the 2nd ac3 onto the same track, this would then hopefully be one big track and the audio would be OK when playing the extras.  This is not that important but it will help the next time I am faced with this situation.

How do I join ac3 files so they can go onto same track in Maestro?  I thought the way I did it would be ok but apparently not.

Thanks for any help.

To place 2 audio tracks in the same field in Maestro, right-click the audio time-line (while its still blank) and choose quot;Sync Audio Trackquot;

Audio tracks used for each PGC are defined in the IFO file  - if you're familiar with IFO edit you can just use this to make the DVD use the right audio track. The first number used for audio tracks is 0x80 - chances are this trailer uses 0x81 or 0x82 - you need to make IFOedit map the right number to the trailer.

The other way of doing this is using Scenarist, but again, this requires the use of IFO edit too.  Check out the IFOedit forum for help with that
