I used dvd shrink and anydvd to rip the movie and used clone dvd to burn it using write mode.I played the back up in my stand alone player and every now and then the volume would drop and raise back up to normal.
I double checked it using my computer dvd player and the sound is fine.This is the first dvd I had this happen to.
I backed up the entire movie plus menues and extras.
Does any one know what may have happened?
