Is there some way to play music and videos from my wii, like not from the internet. Like can I download music/videos to my wii?

I’m planning on getting a Wii but i want to know if it could play DVD’s, music, videos and mp3’s.

Is it possible to get wii music videos on the computer? I made this really nice video and wanted to know if its possible to get it on the computer?

I just got the Opera browser thats found on the internet channel. I can't however play music videos on it, and my internet is yahoo on the go or something. But all the other pages are working pretty great. Any suggestions or solutions?

Thank you, all is pretty fun on the wii, but I want my videos on the tv just for fun.
Yahoo doesn't support it yet, some firefox versions can't play videos either, and yeah I can play videos from other sites such as miitube or youtube, thanks to all!
