Simple, just used DVD authoring software like Sonic DVDit or any DVD authoring software.
Latest nero edition already had Nero Vision for Simple DVD authoring.
If you had problem converting MPEG4 to MPEG2 (DVD Standard compression), then you can use FlaskMPEG or VirtualDubMOD.

Suggestion demux first all 6 channel sounds into 6 different wav files before mux it with DVD authoring software.

Used this software to Mux 6 Channel audio : Soft Encode Dolby Digital 5.1 Channel (Sonic Foundry, http://www. sonicfoundry.com).

If you had AVI with AC3 sound embedded, then you can extract it using NanDub or VirtualDub with Audio Direct Stream Copy enabled, then save it as WAV file. After that just rename .wav into .ac3 and then use AZID to extract 6 channel sound out .

Note : You must have AC3 codec installed properly first before doing that ! Just grab the right codec at Tsunami codec Filters pack.

Default To cypher007

The simplest way to extract the .AC3 audiostream from your .AVI, with NO additional conversion necessary, is to:

1) Load the .AVI into VirtualDubMod (NOT "plain" VirtualDub)

2) From the "Streams" dropdown menu, select "Stream List"

3) Highlight (if more than one audiostream) your .AC3 audiostream

4) Click on the "Demux" radio button

5) Save with a new filename (with an .AC3 extender)

Default ok but

ive got the ac3 ive converted the avi into m2v, but i still cant author a dvd, i either get no sound or some sort of noise like a fax machine. ive now tried using sonic foundry's vegas 4.0, to go from avi with dolby digital 5.1 to dvd, but that says something about the audio stream attributes that it doesnt like.

"ive got the ac3"

1) Which of the several suggested methods did you use to extract the .AC3 audiostream?

2) Have you played back the extracted .AC3 stream by itself (before any further conversion), to see if it plays properly?


As I said in your other VERY SIMILAR thread here, I guess that's one of the many problems you can run into when you're dealing with somebody else's work, rather than videos that you've created...

If you're willing to use a .WAV file, do the following with the original .AVI file:

To convert .AC3 files to .WAV format:

**IMPORTANT - VirtualDub v.1.4AC3 is a specific MODIFIED version of VirtualDub!

Load the .AVI file into VirtualDub v1.4C-AC3, set "Video" to "Direct Stream Copying" and select (under "File") "Save WAV" - and save as .AC3 (IMPERATIVE to save as .AC3!).

Despite the fact that .AC3 file extracted using VDub-AC3 doesn't play properly, PX3AC3Converter (or BeSweet) will do a perfect job of converting it to .WAV format.

(Note: Using VirtualDubMod instead of VirtualDub v.1.4AC3 may also accomplish this properly - I just haven't personally used it for this purpose. I'm sure someone, such as UncasMS, will eventually come along to post whether or not this is correct)

Default update

whilst looking at the audio stream in virtualdubmod i noticed it lists the description of the audio track. it reads "avi audio stream 1 (tag 0x2000,ac3), i think this is why all my programs wont work with this audio file. is there a way to edit the description or run the audio file through a program to fix it?

Default update2

ive extracted the ac3 using vdubmod and then re-loaded it to look at its attributes. they are as follows: ac3 5ch 48000hz 448.0kbps (bitstream v8). so it has changed it on demux, why dont the programs like it then?

p.s. ill try vdub 1.4 ac3
