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...

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.

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....

[John Rofrano]"You need to find an AVI demuxer to split the streams.

Whatever you do, just don't CROSS the streams. It would be bad.
Seriously though, it sounds like what you're trying to do probably has a solution somewhere at www.doom9.org. They have a lot of guides and freeware applications that should apply to what you're trying to do.

Hey guys,
I d/loaded avimux-gui. I extract the binary from the ac3 portion of the avi file. I checked the extracted ac3 as having 6 channels. So far so good. I opened it in DVDA 5.0 and it recognises the file. So far so better.I'm currently burning it and I'll check if the surrounds work on my home theatre. i'm confident it will. then I get to say so far so best.I'll keep you guys updated on the results.
Thks a lot!!!
