I'm having some trouble here

[Bodine]

(Starfox pun intended)

My Wii's pissing me off. :/ It plays most games but it wont play my Metroid Prime Trilogy or Super Smash Bros.: Brawl. The two game disks are completely fine by the way, they can be played on my brother's Wii just fine, my Wii's just being a dick. So what's up with it? It just not a fan of Metroid or Smash Bros. or what?

Did you buy the wii new or not? You could also call the service number in the instruction manual. Try cleaning the disc

Could be a dirty lens. You may be able to use the lens cleaning kit to get it working again.

Nintendo has specifically addressed read errors with both of those games here:
