OK. I'm having a problem with a DVD project edited in Vegas7 and authored in DVDA4. Whenever I play the DVD, with any of the Dolby surround modes on my receiver enabled, the Voiceover is muted. The music sounds fine, it is as if the Voiceover track is muted, which should not be possible at this point. If I disable Dolby processing, everything is fine. The Voiceover is very clear and the music bed plays along just like it is supposed to. I have been able to re-create this on several different audio systems with different manufacturers etc. and the common failure mode is Dolby processing.
In the Vegas project I have a track of stereo music and several tracks of voiceover under the video tracks. The voiceover was recorded as two channels of mono voice, ( not stereo ) and laid into an audio track with two channels. I used multiple tracks because I applied some different effects (EQ, reverb, etc.) to various parts of the video and it was easier to apply the effects to a track rather than to each audio event.
I then rendered (or encoded depending on who you ask) to mpg2 using the NTSC DVD template with the audio included using the template settings in the audio tab.
Then in DVDA, I "prepared" the project using AC3Stereo (NOT 5.1) for the audio setting. Of course DVDA re-encoded the audio because it said the audio stream provided by Vegas was non-compliant.
I am at a loss. I have done dozens of projects this way and have never had this effect show up before. This project is a Promo video for a local non-profit and the way I found out about the problem is that the client called and said " Hey, I went to show the video to a group and there was no narration. The music played, but there was no voice." I said, "Impossible, it is all on one track."
I stumbled onto the Dolby processing issue by accident at home trying to find out what was wrong with the client DVD....... I hooked 7 different DVD players to my system and never got it to fail. Then by accident I changed sound modes on my receiver and bingo - music with no voice. I cycled through all of the "psuedo" modes and all the Dolby moeds failed. DTS and NEO all worked fine.
Any ideas what may be happening?
Any ideas how to prevent this?
P.S. The client is being very nice about this and I am working on another project for them, of which I did a quick render to test things and guess what, the voiceover is clearly audible in that project in all modes including the Dolby modes. ( all using the same templates and settings as the failing project............
Any and all help is greatly appreciated.
