a little more details please...like what format you're burning to dvd, what you're using to burn to dvd...more details the easier it is to understand what your problem is
OK. Say for example i downloaded a dvd rip off bearshare and the result is a great picture and great sound. I then go to VSO'S COPY TO DVD and it starts up and then converts and then writes the dvd. The picture is still great but the volume is greatly reduced.
since I've never heard of or used VSO, I don't really know what to tell you. All I can do is suggest using one of our many guides here to help convert your movie file to a DVD using other software, like tmpgenc. http://www.afterdawn.com/guides/
