Mplayer CE and SMB + Windows 7
I did a bunch of searching, but i couldn't find any definitive answers. Hopefully this will help others get Mplayer CE and SMB working on Windows 7.
First thing you need to do is turn off "Password protected sharing". To do this, click the internet access icon in the lower right taskbar and open network and sharing center.
Now click "choose homegroup and sharing options" and then click "change advanced sharing settings". Now scroll down to "Password protected sharing" and turn it off. Save changes and close the window.
Now go to the folder you want to share on SMB and right click and choose properties, then sharing tab. Choose "Advanced Sharing" and put a check mark in "share this folder" then click "permissions".Now click "Add" and then "advanced" then "Find Now" and scroll down and choose "Everyone" and click "OK" and then "OK" again.
Make sure to put a check mark in Allow Read and click "OK" and then "OK" again. You should now be down to the original properties window. Click the "Share" button and in the drop down box choose "Everyone" and click "Add" then click "Share" then "Done" and then "Close"
If you have your smb.config set properly you should now have access to the folder you just shared when you start Mplayer CE.
