I think I'm seeing the same problem.  When I play certain video files with 
mplayer and "-ao oss", the video plays much faster than normal, the audio cuts 
out, and my audio driver gets called the STOP command at the end of a period.

See my thread, "Any OSS changes from kernel 2.6.21 to 2.6.23? Something broke.", 
although I no longer believe that this is a problem only with newer kernels.
