i have found it best to copy the installer script to your harddrive and run it from the hard drive instead of from the dvd.
Other tricks i have used when encountering the dvd mount problem:
open another console, and as root, type:
Code:
mount /dev/dvdrecorder /media/dvdrecorder
or whatever the path to your dvd drive device and respective mount path
to unmount and unlock the drive after installation:
Code:
**as root**
umount -f /media/dvdrecorder
hope this helps. If not. search the forum, it has been addressed several times.
