Is it possible to encode Dolby Digital 2.0 Stereo for DVD-R?

Hi!

I was just wondering if it is possible to encode to Dolby Digital 2.0 Stereo for using with a simple DVD-R. The reason why is of course the supperior quality to MPEG conversion. Let's say you have a high quality stero wav file, maybe we want to keep that quality and make a Dolby Digital 2.0 file out of it. Also Dolby digital 2.0 works better with Dolby Prologic to simulate 5.1 surround from an amplifier. That's why I'm asking this. Can it be done?

I'm not an expert on this(or anything else for that matter ), but I would have to guess that the answer would be no. It seems to me that when a dolby digital sound stream is converted to .wav, then the digital signal is lost. But then again, I may be wrong. Like I said before, I'm no Thomas Dolby.

Hmm. You might be right. But I mean, there must be a way to create a new dolby signal. So technically I think it is possible. There are also avi's with 5 channel sound. Maybe you can make dolby digital 5.1 of these ones? The question is if there is a program that can handle it.

I no that sonic dvdit Pe has a ac3 audio encoder do you need to make
a 2.0 dolby stereo or do you already have 2.0 dolby stereo just need to put it on dvdr i have put dolby ac3 5.1 on dvdr , might help

I actually have two things. In one case I have an mp3 with 2 channels(stereo). I guess this could be encoded to dolby digital 2.0 in some way? In the other hand I have I guess an ac3 file(in virtualdub file information it says audio: 5 channels, stereo, 48khz), and I don't know what to do with this, is it an mp3 encoded as 5.1, and can it be encoded as dolby digital 5.1?

Baldrick put together a guide for doing just this using BeSweet. See it here:

note: Be sure to read the entire thread before encoding all of your files using BeSweet, there have been some compatibility issues.

Thanx for your help mp3superfreak. I was successfull converting the AC3 from an xvid file to DVD-compliant AC3. However, I found this very strange. When you watch the xvid, sound works perfectly. The problems came when I extracted the audio. Tried two thing: Extracting with virtualdub and extracting with DVD2SVCD. The extracted AC3' both refused to play in any way(windows media player and so on). I found this very strange, though I did not give up. I used the guide you recommended, and my first experience was that the audio file extracted with virtualdub wasn't able to be reencoded. The program did nothing when I hit the conversion button. I tried to change .wav to .ac3, but It didn't work. Secondly, I tried the file extracted by DVD2SVCD. This one I was able to reencode. But now something else came up. I followed the guide exactly (only difference was that the file was .ac3, not -wav). My encoded result would not be played either. I tried one more thing. I checked the "Create 5.1 AC3"-button under AC3 & OGG (this one is left unchecked in the guide). After having done this my result was playable in windows media player, and when authored and played in winDVD, it worked as well.
I find this very very strange, and if someone can explain it, I would be glad, because I can't unerstand what I've done here, and why it worked in the end. Any ideas?
