DVDx and MPlayer problems with HBC?

After downloading the Mplayer and DVDx for the Homebrew Channel on my Wii, ocarina stopped work. Now when I click on Ocarina, it says "not valid Wii application". I tried deleting and re-download Ocarina on my SD card, but it still does not work. I also downloaded various emulators for the Hudson's Bay Company as Snes9x GX. Has anyone has been such a problem after downloading an application to the Homebrew Channel? What could be the problem and how can I solve this problem? Thank you.

Did you upgrade to 3.4? If so, he beat a number of homebrew applications. This could be one of the victims.
