AVI 6 Cahnnel to DVD 6 Channel

[doggyofone]

I've had problems with these conversions. The original AVI is encoded with Dolby, 6 channel. When I convert with VSO DIVX to DVD the sound track was greatly accelerated, not even close to the video, but was converted to DVD 6 channel. The original was 384kbs, 48000 and was converted using these settings. I have a number of compatible codecs available. Perhaps one is causing problems.
I've had the same issue with Soft Encode when trying to convert WAV to 6 channel.
Is there a program that will convert AVI to DVD format or Mpeg DVD compliant that will maintain the 6 channel output? I've tried a number and currently testing TMPGENC 3.0 with the AC3 plugin.
DVDlab will author 6 channel, but I've got to have a 6 channel audio file, or re-encode with Besweet.

If you have already Doldy Digital (DD) 5.1 ac3 file in avi you do not need to reencode it as it is DVD compliant. You are wrong if you think that DD ac3 5.1 in avi is something different. The original avi was not encoded with this sound, but just multiplexed with it. So you need an encoder that can reencode video elementary stream only to DVD compliant mpeg2 video elementary stream only. This can not be done with Divxtodvd. Your experiments with TMPGEnc Xpress 3.0 with ac3 plugin are pointless if you try to reencode the audio stream also. You can use TMPGEnc Xpress 3.0 to encode only the video stream. Then you give the both elementary streams (reencoded avi-to-mpeg2 video stream and the original ac3 6 channel audio stream) to DVDLab

Thanks Abond.
What program would you use to demux the audio from the AVI? I suppose Cinemacraft would do it.
Once I have it and an Mpeg video I can pull both into DVDlab. Do I need to worry about sync at this point, because the mpeg is a lot larger than the avi?
I'm trying to learn this and avoid using the all in one programs.

VirtualDubMod for demultiplexing the audio from avi. Click Streams-Stream list and then click demux button. CCE would not demultiplex an avi. It is encoder application.
File size has nothing to do with sync. You should look the duration - hours:minuteseconds.

Abond, thanks again. Another question, do you know why the original DIVX to DVD sped up the AC-3 sound track? It was much faster than the video. The program screen read the file as an AVI AAC-3 6 channel, 384 /48000, but encoded it a very high speed as compared to the video.
CCE wil produce an MPV, MPA file. Can I use the mpv as my video and the virtual mod demux for the audio?

If your audio is really AAC 6 channel, then no, you cannot use it for DVD. DVD require AC-3 or mpeg layer 2 audio (MPA=mpeg audio file). Audio engine of CCE is not good, do not use this output.
Now if your sound in avi is AAC then it can explain why DivxtoDVD makes it wrong - it doesn't handle AAC input corectly obviously. Then what was written in VirtualDubMod for the audio file? AAC or AC-3? They are quite different...
