OK, that is an mplayer problem does a driver problem.  The mplayer 
program supports multiple output back-ends and it either can't figure 
out what to use or what it is choosing isn't working.  Run "mplayer -vo 
help" and you'll get a list of all the choices.  Two choices that are 
likely to work in all cases are "-vo x11" and "-vo xv".  The second 
choice is preferred because then it will be able to scale the video 
using a hardware scaler on the GPU.  But if "-vo xv" doesn't work then 
certainly "-vo x11" will.  I also suggest you find some nice mpg video 
clips somewhere and just try to play those with mplayer.  Then you can 
debug mplayer issues separate from pvrusb2 driver issues.  Once you have 
something that works, you can write these options into ~/.mplayer/config 
(or something like that).  Check the man page for mplayer to find out 
more details about all of this.  I wouldn't even bother with kmplayer 
until mplayer itself is working first.
