I am having problems accessing data on DVD's I have burnt, they burn ok but when I try and look at the data on the disk it just freezes. In My Comp the drive icon indicates a disk, when I click on it it opens to show the thumbnails for the files on the disk(video files)but when I click on one the drive light flashes to indicate its reading the disk but nothing happens, sometimes media player will open to play the movie file but it doesnt play. Its not the drive, I had the problem with my last drive so got a new one and it does the same. Any ideas?
