Subject: AC3 Encoding not working in DVD Architect

Well, to say the least, I am a wee bit miffed (or I am stoopid!). I bought and activated the Sony AC3 encoder and it works Ok within vegas 8 Pro. However, the only time I can actually hear the results of my surround mixes is when I render it as a wma/v file. It then plays 5.1 on all the players I have.
My problem is when I take it to DVD Architect to burn a 5.1 surround DVD. No matter how I set this software up, I just cannot get it to play back in 5.1. What is up with this? It just puts everything in stereo! Boring. I have tried every way of rendering it but to no avail. And the manual is no help either.
What am I missing? If anyone can help, I would REALLY appreciate it...
Thanks, makatini

Same thing here but with
Vegas 8 Platinum 8.0c build 136, and DVD Architect 4.5c build 91,

I can preview video clip and 5.1 tracks from the editor (in Vegas), all vue meters are working ok , (up/down), when I choose to make a movie,vegas's suggesting to "directly start DVD Architect" since I have allready render with Dolby AC-3 5.1 surround sound template (as suggested also from vegas user manual), but when I'm into DVD Architect, my audio track are back to 2.1 stereo downmix.
and on the preview monitor I can see only a stereo track. but the icon
at the begining of the audio track show 4 speakers in a square.

Iv'e been trying many option, and looking many times trought the manual, help files, and no luck!

I supposed that Sony Creative Software is aware of this problem,
hope to get a simple fix, or the right instructions to resolve this problem.

I'm looking to get the profesional version, but since there's some problem with this version , I'll hold until this issue is fix.

I had this issue but found that if I rendered the audio as a separate 5.1 track in VEGAS, then made sure that DVD architect project properties were set to AC3 5.1 ( not AC3 Stereo), this stopped DVD Architect from recompressing the audio and I got 5.1 on the DVD.

This is the situation as I understand it:
Vegas & DVDA have AC-3 Encoder, but NO AC-3 Decoder.

When you drag an AC-3 Encoded file into DVDA you see the 2-track Encoded signal for monitoring and sync purposes only - the playback is not AC-3 or Stereo.

To playback (Decode) an AC-3 file you need to install a 3rd party DVD player such as InterVideo WinDVD - correctly setup this program will play and decode the AC-3; additionally it's codecs will be become available to Windows Media Player if you have it setup for multichannel (5.1) output: therefore that will also play back decoded AC-3.

HI ChristoC

I think I have the same problem. I shelled £1K for the hard disk video recorder SR8E when it was pretty new. Since then I've been using Nero Vision for producing DVDs. I wanted to do something better for myself, so today I shelled out £100 for DVD Architect Studio 4.5d and two of the vision series backdrop kits etc.

My recorder always records DVDs in AC-3. My event last weekend is thus encoded. Are you saying that if I write the dvd despite not hearing it in preview mode, the sound will still be preserved, and my finished written disk will still have its original audio track?

Thanks!!!

That is correct.

DVDA previews in stereo and outputs in whatever you give it, assuming your project properties are set correctly.

None of the Sony applications have built-in 5.1 decoders.

And is there a way to decode AC3 into Vegas?
As far as I remenber, that was posible in the past by simply drag .AC3 track into timeline.
