burning file with 5.1 audio in DVDA
I’m trying to burn to dvd a movie file that has audio with 6 channels (dolby ac3,5.1). According to gspot, I have 3 compatible audio codecs installed to view this file. Rightly so cos my windows media player plays it just fine.
Now when i try to click on this file via the explorer in DVDA, i got the hated ‘audio stream attributes could not be determined’.
Cleverly I thought I could convert the audio file to something compatible to DVDA. Magic converter converts it to 5.1 but the audio was stretch by about 30% of the running time.So tell me how can I achieve what I set out to do? I just wanna burn into dvd a 5.1 surround movie and get to enjoy the surround on my home theatre system. Any help is superly greatly appreciated. thks.

Obviously DVD Architect doesn’t like something about that AC3 file. You were on the right path to convert the audio. I would do it in Vegas using the AC3 5.1 Surround template. This way you will be sure that it is encoded correctly for DVD Architect. You may have to figure a way to get it into Vegas first like converting it into 6 wav files.

John,
Thks for the response.
Getting into vegas is THE problem too. Apparently the file is not Sony friendly. I can easily convert it to mp3 stereo using Magic and bring it to vegas or dvda.But that will defeat the whole purpose as I would lose the 5.1 surround. if I understand this correctly 6 channels mean 6 audio files. So how do i break it into 6 different wav files? Any software that can do this? hopefully free.

Steve,
Yes I do. I’ve installed soundforge 9.0.
I’m not familiar with soundforge but I tried opening the file with it and was not successful. It doesn’t recognize the said file. It indicated no audio. But video is ok. Any other solutions? pls… -
So… where did this file with the mysterious AC3 come from?

Hmmm… ok so it’s basically an “unknown” source. You can try to convert the AC3 file to a multi-channel WAV file using a tool like AC3Tool. If you do use AC3Tool, go to the AC3 > WAV tab and set the Downmix mode to 3/2 “5.1” then press the AC3 > Wav button at the bottom right.
This will create a single WAV file with 6 channels. Just drop this file into a 5.1 Surround project in Vegas and it will lay out the 6 tracks. Then you must manually pan the tracks to LF,RF,LR,RR,C,& LFE. Finally render as AC3 5.1 Surround and DVD Architect should be happy with the file.

Yes John, that’s a handy little tool for ac3 formats that are
a bit stubborn.
That should prove helpful to Zack.Steve Rhoden

John,
I tried to do exactly what you said. But the ac3 is actually in the said movie.avi file. So, how do i extract the ac3 in the first place? Cos under the tab ac3 analysis, it only recognizes ac3 files.
My audio is in an avi file. How??? pls enlighten…. -
> So, how do i extract the ac3 in the first place?
You need to find an AVI demuxer to split the streams.
