I'm kind of new to this and I've just notice that on movies backed up with dvd-shrink and burned with Nero Express DVD-Video burner everything plays fine in my dvd player but when I put the disk in my computer and try to access the dvd-rom extra features nothing happens and I get the same note as if I was just watching it on my dvd player. How do I get these features to burn too? I've noticed that there is also a Nero Burning Rom should I use that since it has a dvd-video option also...keep in mind I have no idea what the iso option is for. Any help is appreciated! Also with my new batch of disks they're burning way to fast at 16x instead of 8x so for the first time I'm getting burning errors but I can't find where to change the burning speed setting in nero, does anyone know?
