I have a number of video files that I'm trying to view in MPlayer and/or
KMP.

MPlayer simply can't get through them without crashing in decode_audio,
usually within a few minutes or even seconds.

KMP can play them for longer, but eventually the sound suddenly cuts out
and never comes back. (This usually seems to happen when the video hits
a point where it maxes out the load and stutters slightly.) Sometimes, KMP
crashes as well.

Is this likely an issue with the files, with MPlayer and KMP, or with my
sound driver (Uniaud 1.1.4 rc4)?

FWIW, here's the output from MPlayer:
