self authored DVD only works with PCM sound in standalones

[Dreamweaver]

Hi everybody!

Having some strange sound problems I am not capable of solving :(

I created a self authored DVD from movies I made through the time. Therefore the sources were mostly tga sequences and a wave file.

I encoded the tga's as lossless huffyuv for further editing purposes. These huffyuv's were then transcoded with CCE 2.66.01.07 with the following settings.

The audio was upsampled with CoolEdit 2000 to 48kHz and then transcoded with AC3Machine to AC3 sound. The settings where as shown below.

The whole thing was then authored in DVDMaestro. Well, just dragged and dropped the movies in the movie part of the timeline and the sound in the first audio row for testing purposes. There I compiled it and created the image with ImgTools 0.89, then burnt with DVDDecrypter 3.1.6.0

In my software player (NDVD) it all plays just fine, but my standalone (Pioneer DV-717) just plays the files without sound correctly. The movies with sound play fine as long as there is no actual sound hearable. But when the first sound is to be played the movie hangs. On can play forward or backwards and the movie then plays a few frames with sound again, then stops again.

I tried different settings like turning of the DVD compliant checkbox in CCE or lowering the bitrate in AC3Machine to 192 and stereo output, but nothing changed. The I tried using uncompressed PCM sound and it works! But that made my soundfiles unreasonably large :(

Any ideas how to solve this?

Never check "DVD-compliance" in CCE, it results in the maximal bitrate being set to 9800, therefore leaving no room for the audio...
The multiplexed bitrate can not exceed 10.08 Mbps...
But since PCM works, it seems that this is not the problem...
Your AC3machine-settings are not entirely right...
Why do you have ac3 as input???
You said it was wav, right?
You don't need to upsample with cooledit, let AC3machine do it (you have already checked it: SSRC 4800...)
The lfe2lr-3db setting is only useful for converting 5.1 to 2.0...

So try feeding the wav directly into ac3machine, leave your settings as they are, just uncheck lfe2lr-3db...

I personally always use ac3enc which is included into scenarist...
If you have it, try that, just seperate the channels with cooledit (convert sample type, save one time with 100%left and one time with 100%right), and feed the two mono channels into ac3enc...
AC3machine is great, but i usually feel that the output volume is a little bit too low (i think it is a problem of the ac3enc.dll used by besweet)...

sorry my fault.
of course I used a wave file, the screenshot was incorrect, but the rest of the settings are correct.
Ok, I'll try leaving LFE2LR unchecked.

I don't have Scenarist, is this tool ac3enc freely available anywere?


The bitrate setting is not the problem. I patched it with DVDpatcher to 6Mbps and it still doesn't work.

The bitrate setting is not the problem. I patched it with DVDpatcher to 6Mbps and it still doesn't work.
DVDpatcher only changes the nominal (nominelle) bitrate (not the "real" bitrate, in case the authoring program demands a specific value...
But since pcm works, this isn't the problem...
AC3enc isn't freely available I'm afraid...

the trick with unchecking lfe2lr didn't do it, sorry ultimatebilly :(

any other solutions available?

Well, in fact it was the checkbox DVD compliant. It sets the nominal bitrate to 9.8 Mbps, which I patched to 6Mbps (which is a custom value in DVD patcher).
But when I switched to a standard value of 8 Mbps in DVDpatcher and patched the entire file (!) it works.
