I am not at all convinced your hangs are related to zram or swap. Fire 
up top in a terminal with 1 second refresh and watch the memory usage. 
If the free memory suddenly drops through the floor, then maybe memory 
pressure is relevant (but the root cause is still a bug in the 
application). Otherwise, I'd probably look at a big in the audio 
subsystem somewhere.

Just out of interest, you haven't tweaked the default cache size setting 
on mplayer, have you?
