No Audio help please ????

[gmpman]

I just authored my first dvd and I have no audio. I have made many *.svcd so I am fairly used to most of the programs. I followed this guide for conversion

http://www.donstevenson.net/myguides/myguides.html

and this guide for authoring

http://www.donstevenson.net/DVD_Architect.htm

the *.VOB's play great on my computer with audio, and when I play the dvd in my standalone DVD (pioneer dv-440) Video is awesome but no AUDIO.

I checked the settings on my dvd and they are set to PCM. When I press the audio button on my remote, I get the message that says "Dolby digital 2 channel"

Can someone shed some light here?? I am baffled....

BTW

I just loaded the DVD into my computer and "opened" it. It shows audio and video TS folders.

It plays through WIN DVD 4 but has no audio there either, once again the video is great.

It helps to elaborate more on the process you did. Walk through on a step by step basis. What programs did you use?

[gmpman]

My process is as follows:

open the avi with g-spot
Scan the avi for bad frames with Virtual Dub
Save the audio as *.WAV
Save the video with No audio as *.avi
Converted the *.WAV file to *.AC3 with AC3 Machine (the source audio was 44100 so I checked the Set sampling rate to 44,800 hz box)
Open avi with FitCD to get *.avs script
Load *.avs into CCE
Use bitrate Calculator to get values
Enter values into CCE (Mpeg-2 ES Multi-pass VBR)
Set video and quality tabs
Encode with CCE
Source video was already at 29.97 so no need for Pulldownbatch FFE
Multiplex the *.M2V and *.AC3 files with TMPGEnc to get *.mpg file
Load *.mpg file into DVD Architect and select *.AC3 as the audio file
set my chapters and click on prepare and burn DVD.

Got no error messages, nothing needed compressed or re-encoded

What I got was a great looking dvd but no audio.....

Hope that helps

audio in virtualdub should be 48,000 hz

[gmpman]

when I opened the file in virtual dub, the audio portion told me the audio was 44100hz. I resampled to 448000hz in AC3machine. Are you telling me that isn't correct?

[gitreel]

yes because dvd audio is 48,000 hz

I don't know if I'm getting in over my head here or not. I'm just wondering why you use such a complex method at all. My method would be something along these lines:

1) Load avi into Pinnacle Studio 8. Make DVD

or

1) Load avi into Tmpgenc and convert to mpg
2) Load mpg into Tmpgenc DVD Author and make DVD

Is this a question of freeware versus vs non-freeware?

[gmpman]

oops, I did resample to 48000 hz not 44,800hz. My bad. It still didn't work. If I had the wrong type of audio file I would have gotten an error message in DVD Architect....

Still confused

Did you check that the individual ac3 can play. Why did you multiplex the m2v with the ac3 to a mpeg. This is surely going to give you problems. Any good authoring program should accept the two streams separately to make a dvd. Also there are known issues with your ac3 conversion program and pioneer dvd players but this is not your problem since it will not play on your computer.

I might be wrong, but the reason for multiplexing the sound with the video is because you get a better result encoding sound and video seperatly than you do if you use a prog like TMPGEnc or similar to do both at the same time.

Also you mention that the vob file plays with sound on your PC but the disk won't. Are these both through Win DVD 4? If so it sounds like something went wrong when you actually burnt the files to the DVD. Try using a different burning program, and / or play around with the burining speeds..

If you have one bad peice of data in your ac3 then a lot of DVD authoring software will not rencode it, download besplit, run bespliced exe, (a postage stamp size figurehead will appear) drag your ac3 onto this and click on fix, use the fixed ac3 in your authoring software and see if that works
