I installed MPlayer CE and I am able to watch DVD movies and avi movies (from USB FAT32 flash drive) but I don't know how to set up the file sharing. I have a share that I can access on my Xbox using uShare but when I try to put that same file path in the smb.conf file for MPlayer CE, nothing happens on my Wii. Here's how I have the conf file set up:
#Samba share1  (smb1:/) 
user1= kenny
All of that information is correct for the computer where this folder is being shared from. Is there a certain IOS I need to install to enable this feature? Is there some software I need to be running on my computer for the share to work?

I'm using Ubuntu 10.04 and Wii 4.2U (a list of all my IOSs can be found in the last thread I started on this forum).
