I'm trying to do 2 things.
 

I'm trying to mount my dvd player on my windows box. I know you can use the mount command to do this, I think. The question is how? Also, I downloaded Netscape 7.1 and I currently have Mozilla installed. Netscape installed okay and it works. In order for it to work, I have to go to the directory and execute it by typing ./netscape. Is there a way I can create an icon on the desktop and a quick launch button. Any help is greatly appreciated.

In regards to the dvd thing you can probably just type:
mount -v /dev/cdromX /mnt/cdromX (x is the dev number)
or you could make a link to /dev/cdrom from /dev/dvd as for the filesystems mount will check /etc/filesystems to see if you can read dvds

As for netscape you could either put the directory the binary is in, in the search path or you could make a symlink from /usr/local/bin/ to the executable eg.
ln -s /the/netscape/binary /usr/local/bin/netscape-7.1 ( but then you'd need to run netscape as $netscape-7.1

Creating a shortcut on the desktop is just the same as making a link to the desktop and a quicklaunch you just drag it into the quicklaunch.
