This complaint, most of the time comes from movie downloaders. The issue doesn't show up on legitimate content. For example I use Keedvid.com and a video from google video then DVDSanta works fine.
If the audio goes out of sync, tell how you made the source video so we can look at how to prevent that.
I had videos on my hard drive that i would like to burn to DVDs what is the best video burning software so that the sound isnt thrown off so much...right now i use Cucusoft and a program called Movie DVD Maker, but they arent very good.
Which ones do you guys/gals prefer?
