Hello, I have a project in DVDArchitec, but when listening to it in a DVD of hall, I listen to the audio one with echo I use the Ac-3 but not that it happens, because the same project I do it with the DVDit and it is listened to better.
Does the DVDA produced DVD have ac3 audio?
If so that would explain the difference, DVDit (as afar s I know) doesn't use ac3 audio.
If that is what's causing the problem you have one of two choice.
Use PCM audio for your DVDA DVDs but it will atek up more space on the DVD or
You will need to adjust the settings on the ac3 encoder to get it right. I'd do a search on this and the VV forum for links to tutorials explaining how it works and how to get it right.
