Great Peter!!!
In option 3 ("Explorar") I forgot to mention that the word "un" does not belong there, just "Explorar DVD" ("un" in this case would mean "any", and we don't want to explore "any" dvd but the dvd we are using atm, that's why "Explorar DVD" is the correct expression).
Another doubt I have is regarding the screen when you choose wether to install desktop icon or not, there's another option named "aditional icons" or sth like that, what would that mean?
Kind Regards (hope this little "tweaks" does not bother you, I'm trying to put my grain of sand to your great convertions...)
