I don't know about the others, but the "xrun" error usually indicates
that mplayer can't read the file quickly enough, and the audio buffer is
getting depleted. The usual fix is to add -cache=1024 or some other value.

Considering that you're using alsa 1.x, and if the xrun error always
occurs in conjunction with the other two, it's probably just an
indication of a bug in mplayer's alsa 1.x support (which hasn't been
around for very long). You should read:

and fill out a complete bugreport.
