nitoTV in main menu twice

Can someone help?

the nitoTV is in the main menu twice.

the AC3 passthrough (even though it is set) doesn’t work (gibberish buzzing from Quicktime when playing video)

Perian was updated as of today.

everything plays fine with XBMC

mplayer…never got it to work. Additional codecs seem to never install (can’t tell)

On the menu thingy…please direct me to the menu.plist to fix (please don’t tell me to re-install from factory…I’ve done that already and everything is working well (AFP, etc) and I don’t want to start over. Well…except mplayer)

ideas? thoughts?
