A few months ago I started burning VCD's for the first time. I researched a few basic techniques here and at other forums and began. Here's my question: at a different forum they suggested using V-dub to create a separate .wav audio file for TMPGEnc. So that's the method that I've been using. But, I've noticed that the re-encoded MPG result has a significant loss in audio quality over the previous AVI. In an article here about encoding music videos, you suggested using the original AVI for both video and audio imput. Is this better? I have tried to find other articles about this, but have been unsuccessful. Which method produces the best result?
