how do i know if my dvd drive is dying or if it is another problem? ive burned a lot of movies, some older movies, some newer.. several of them lately say they have finished and i go to play them and it says cannot read disk. i checked some and it seems like there was nothing even burned onto the disk because i took one and tried to re burn it again onto the disk that says it was used and it worked. so is my burner dying >? or is it something else? why are my movies not burning when they say they are? is there copy protection that makes it so it wont burn anything for you to disk? my burner is 3 yrs old. laptop. i also have a desktop drive that when burning a movie, also might not burn, also it looks like it burned weird cuz its discolored on the back . any suggestions?? i usually use verbatim blank media disks.
