I apologize in advance if this is old news, but I recently came across this article. Supposedly, following the ISO burning procedure outlined below will make a DVD less susceptible to errors from scratches or defects. Does anyone currently use this method? I'm curious if the 32k gaps are part of a dvd "spec"?
