Ok I have been using sites to watch movies online, but it seems like most of them make it impossible to use the Wii now (for some odd reason). Well I made a site www.showflick.com that will auto recongize the Wii and go into "Wii mode" currently I have close to 200 cartoons and movies (all legal) that can be watched with the Wii, I plan on adding more. I did this because I am a Wii nut.. I hope you enjoy the site.
Go to your internent channel and enter www.showflick.com in the web address bar.
