Just set mine up in 10.6.8. The steps were just a hair different:
1) Go to > System Preferences > Sharing
2) check the box next to “File Sharing”
3) specify the folder/s you want to share to the Wii in the window in the middle named “Shared Folders”
4) set User preferences in the “Users” list in the window on the right
5) click the gray “Options” button on the right above “Users”
6) check “Share files and folders using SMB (Windows)”
7) make sure you check which Accounts you are sharing in the window below
8) click the “Done” button
9) Quit System Preferences
and you’re all done. My AVIs stream wonderfully.
