im not sure what the trouble could be, but for some reason im having problem writing the final step of a dvd. i sucessfully rip the dvd to my hard drive using dvd shrink. then ive tried several programs to burn....nero, roxio, shrink and each one fails at the very end, rendering the dvd unreadable. nero gives an erro "unable to write disc at once, lead out"

any ideas ??

thanks everyone !
