Help Please !

while the BuzzTV app is open and working, use the menu button to bring up a side-bar menu onscreen.
Scroll down to Configuration, open that and you can switch between the default and the other Player
 
It seems as if the "Default" to be the best choice though, although choosing "secondary" started playing the video :) but kind of slow.
I also tried "internal" and "old" which did not appear to be very efficient. :(
