I have burn an DVD with 3 episode from a TV show. But when I'm wachting it on my computer or my TV there a problem with the sound. The problem is the following: At the beginning of the episode all the sound is good but after some minutes their is a lag with the lips of the characters and their voice. The format of the file is MPEG-3 So how could I solve this problem, because it's the first time that it happened to me (I've burn a lot of movies before)??? Should I use another software? By the way, did anybody know another software then NeroExpress vision 3. Thank you
