I'm using miniDLNA to connect my Ubuntu PC with my Asus Transformer. Result is I get to play movies and music from my PC directly on my tablet!!
Here's how to setup miniDLNA on Ubuntu:
1) Get source file from here.
2) Extract and unpack the archive to a designated folder called "minidlna"
3) Edit file "minidlna.cnf" (config file in folder minidlna > etc )
4) From Terminal, go to the "minidlna" folder
5) Type the following command:
username@machine:~/minidlna$ usr/sbin/minidlna -f etc/minidlna.conf
*This needs to be typed in everytime you start the PC

username@machinename:~$ cd Folder1
username@machinename:~/Folder1$To return back to Home Folder:
username@machinename:~/Folder1$ cd ~
username@machinename:~$
To go to root filesystem:
username@machinename:~$ cd /
username@machinename:/$ ls
bin dev initrd.img media root srv usr
boot etc lib mnt sbin sys var
cdrom home lost+found proc selinux tmp vmlinuz
To go up one level (notice there is a space, unlike in DOS where it is "cd.."):
username@machinename:/media$ cd ..

Ubuntu: Write access to files and folders in Live CD session
Usually we'll access the system via Live CD in scenarios where we cannot boot the system normally. So this is where you do troubleshooting, revise config files etc or to backup important data.
You will not have write access to some of these files and folders. To do so, open up terminal and type in the following command:
sudo nautilus
A new folder will open, and you will see this folder is set as root. You now have write access to all files and folders in the Live CD session.
