I am playing MP3s from my itunes playlist using daap etc etc. It will play one then stop when I try to play the next song it crashes and reboots why is this

I had the same problem as you. I think the problem is something with the updated mplayer files. So what I did to fix it was I downloaded the 1-15-05 release and copied over its mplayer folder to the latest release, 2-2-05. So, basically you are just downgrading your mplayer to a more stable state. Hope this helps.
